A human observer cannot tell the difference between two instances of the same characters in a bi-level image even though they may not exactly match pixel by pixel. equal-characters (=) at the end. Select a picture: Password or leave a blank: Decode Clear. It uses four 5x5 squares to translate All geocaching tools a geocacher needs in one box! 8, no. Letters Only Copyright PlanetCalc Version: One of the methods is similar to the context-based arithmetic coding algorithm, which adaptively positions the template pixels in order to obtain correlations between the adjacent pixels. [18][19], Xerox subsequently acknowledged that this was a long-standing software defect, and their initial statements in suggesting that only non-factory settings could introduce the substitution were incorrect. The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by-letter basis in a very simple way. Encode; Decode; Encode message. Step 3: Make the Decoder Function Firstly, we repeat a similar procedure of saving the pixels of the source image as an array, figuring out the mode, and calculating the total pixels. History. It is stronger than an ordinary Playfair cipher, but still easier The image Steganographic Decoder tool allows you to extract data from Steganographic image. Depending on the orientation of the squares, horizontal or vertical, the cipher behaves slightly different. Example, using 3 hidden bits: Bond has been set for a driver in a crash that claimed a mans life last week in Leesburg. | Binary analysis Therefore, only the bitmap of one representative character instance needs to be coded instead of coding the bitmaps of each occurrence of the same character individually. Secret messages can be hidden within plaintext, or something that looks like plaintext, using steganography techniques. 140143 vol. String Utilities. This allows decoder to successfully render a halftone image by presenting indexed dictionary bitmap patterns neighboring with each other. [23], Block diagrams of (left) pattern matching and substitution method and (right) soft pattern matching method. Converts Tsv to plain text and make it more readable. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. The secret information itself can be a message or even another file (picture, video or audio file). information about possibly useful tools to solve it. One of the more difficult variants is the double transposition cipher, which is equivalent to applying two columnar JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group.It is suitable for both lossless and lossy compression. Note: To get accurate results, your ciphertext should be at least 25 characters long. Bond has been set for a driver in a crash that claimed a mans life last week in Leesburg. For further text analysis and statistics, click here. The letter "X" is used to break up sentences, and "K" for acknowledgements. The plaintext letter is The monoalphabetic substitution cipher is one of the most popular ciphers among puzzle makers. To prevent automated submissions an Access Code has been implemented for this tool. Beautifies ugly sql code and makes it more readable. You could extract data from Steganographic Decoder. Morse code also takes longer to learn. makes it especially useful for puzzle games, where it is sometimes not fully obvious that a code is a Morse Code. [21] In Switzerland the Coordination Office for the Permanent Archiving of Electronic Documents (Koordinationsstelle fr die dauerhafte Archivierung elektronischer Unterlagen) has recommended against the use of JBIG2 when creating PDF documents.

Minify SQL code and remove unnecessary spaces. 838848, Nov 1998. The next one-time pad system was electrical. Secret messages can be hidden within plaintext, or something that looks like plaintext, using steganography techniques. Each region is coded differently and the coding methodologies are described in the following passage. Because of the difficulty and length of time required for specifying a single letter, prisoners often devise abbreviations and acronyms for common items or phrases, such as "GN" for Good night, or "GBU" for God bless you.. By comparison, Morse code is harder to send by tapping or banging Other possibilities are that the text is a riddle or using anagrams. Select a picture: The text you want to hide: Password or leave a blank: Steganography Clear. P. Howard, F. Kossentini, B. Martins, S. Forchhammer, and W. Rucklidge, "The emerging JBIG2 standard", Circuits and Systems for Video Technology, IEEE Transactions on , vol. The message is transmitted using a series of tap sounds, hence its name. Gronsfeld ciphers can be solved as well through the Vigenre tool. The Patent Public Search tool is a new web-based patent search application that will replace internal legacy search tools PubEast and PubWest and external legacy search tools PatFT and AppFT. CSS Minifier Some of the most common steganigraphy techniques are the so called NULL cipher and the baconian cipher. Can't find calculators you've been looking for? Instead it begins using letters from the plaintext as key. You could hide text data from Image steganography tool. Beautifies ugly xml code and makes it more readable. For lossy compression the difference between similar symbols (e.g., slightly different impressions of the same letter) can be neglected; for lossless compression, this difference is taken into account by compressing one similar symbol using another as a template. Minify OPML code and remove unnecessary spaces. The railfence cipher is a simple form of transposition cipher, where the text is written in a "zig-zag" pattern. Steganography; NULL Cipher Many can be solved manually | Frequency analysis It was invented by Lieutenant Fritz Nebel and is a fractionating They can also represent the output of Hash functions Note: Your ciphertext is less than 25 characters long. When used in lossy mode, JBIG2 compression can potentially alter text in a way that's not discernible as corruption. An algorithm is basically a procedure or a formula for solving a data snooping problem. This tool uses AI/Machine Learning technology to recognize over 25 common cipher types and encodings including: JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group. The Beaufort Autokey Cipher is not each digraph. Converts tsv to multi-line-data and make it more readable. Image Steganography is hiding information within images. Password Decoder is a simple yet quite useful software solution that can assist you in retrieving the login details for your various email accounts by decrypting the data stored by The Bat! The image steganography tool allows you to embed hidden data inside a carrier file, such as an image. other means such as lines, colors, letters or symbols. pair of letters in the ciphertext depends on a pair of letters in the plaintext. To simulate Morse by tapping therefore requires either two different sounds (pitch, volume), or very precise timing, so that a dash within a character (e.g. Converts Tsv to plain text and make it more readable.

The columns are chosen in a scrambled order, decided by the encryption key. Encode; Decode; Encode message. If your cipher consists of lines and dots, it could be a, If your cipher has runes, you could translate them, If your cipher has hardwritten symbols of men in various positions, it could be a, If your cipher has combinations of colors, it could be a. While being deceptively simple, it has been used historically for important secrets and is still popular among puzzlers. most common steganigraphy techniques are the so called NULL cipher and the baconian cipher. A dictionary of symbols is then created and encoded, typically also using context-dependent arithmetic coding, and the regions are encoded by describing which symbols appear where. JBIG and JBIG2 patents are not the same.[11][12][13]. Remember, the more text you want to hide, the larger the image has to be. By clicking the decode button upload the file that is to be decoded and after uploading the hidden text will be displayed on the screen. Converts csv to plain text and make it more readable. [20], In Germany the Federal Office for Information Security has issued a technical guideline that says the JBIG2 encoding "MUST NOT be used" for "replacement scanning". Patches that comprehensively address the problem were published later in August, but no attempt has been made to recall or mandate updates to the affected devices which was acknowledged to affect more than a dozen product families. The bi-level image is segmented into three regions: text, halftone, and generic regions. [10] They used it to communicate everything from what questions interrogators were asking (in order for everyone to stay consistent with a deceptive story), to who was hurt and needed others to donate meager food rations. Base64 is easy to recognize. 15 . A, D, F, G, V and X. [3] The knock code is featured in Arthur Koestler's 1941 work Darkness at Noon. Gustavo Martinez Cortez, 36, of Eustis, was arrested Nov. 7 after the four-vehicle crash at County Road 44 and North Silver Lake Road when he rear ended a 2004 Toyota Corolla driven by a 42-year-old Eustis man, who died at the scene.Driver among killed * http://opensource.org/licenses/mit-license.php, Set characters of coded hidden text(zero width characters), text: original text to be embedded (String), args: unicode text with steganography (String), //var base = '0'.repeat(codelength); // IE not support this method. November 13, 2022. [11][12] It was even used when prisoners were sitting next to each other but not allowed to talk, by tapping on another's thigh. Remove unnecessary spaces, indentation and newlines. The listener only needs to discriminate the timing of the taps to isolate letters. The two-square cipher is also called "double Playfair". Results are less reliable. ; the. It received the highest scores for indicators such as durability and comfort of employees OMON, SPETSNAZ, SOBR, VITYAZ, ALPHA IN COMBAT OPERATIONS BECAUSE OF HIGH QUALITY, It received the highest scores for indicators such as durability and comfort of employees OMON, SPETSNAZ, SOBR, VITYAZ, ALPHA IN COMBAT OPERATIONS BECAUSE OF HIGH QUALITY, A variant of the Vigenre cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. to use than the four-square cipher. NB: for encrypted messages, test our automatic cipher identifier!. They can also represent the output of Hash functions Convert html to multi line data and Beautify. The Playfair cipher was invented in 1854 by Charles Wheatstone, but named after lord Playfair who heavily promoted the use of the cipher.

JBIG2 was published in 2000 as the international standard ITU T.88,[2] and in 2001 as ISO/IEC 14492.[3]. Like the "knock code", a Cyrillic script version is said to have been used by nihilist prisoners of the Russian czars. Free online SEPA XML validation : This service validates SEPA XML documents against specified XSD schemas. A simple program, located in Internet web pages to perform mathematical calculations. The syntax highlighter, auto completion are also enabled to write code more easily. [22], A vulnerability in the Xpdf implementation of JBIG2, re-used in Apple's iOS phone operating software, was used by the Pegasus spyware to implement a zero-click attack on iPhones by constructing an emulated computer architecture inside a JBIG2 stream. 1, pp. If after a pause there are three knocks, they think "Q R S" to arrive at the letter S. The origins of this encoding go back to the Polybius square of Ancient Greece. Minify XML code and remove unnecessary spaces. From coordinate notation changes to conversions to complete different coordinate systems and from distance calculations to midpoint and intersection calculations can be found here. And passed the test in many special units of Russia. Decimal Codes can represent A1Z26, ASCII, or more advanced encoding schemes. And passed the test in many special units of Russia.

Ethereum smart contract transaction input data decoder. It is believed to be the first cipher ever used. "P" consists of sixteen taps in a row). [9] There are two encoding methods for text image data: pattern matching and substitution (PM&S) and soft pattern matching (SPM). To encode a message into an image, choose the image you want to use, enter your text and hit the Encode button. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Typically, a bi-level image consists mainly of a large amount of textual and halftone data, in which the same shapes appear repeatedly. To encode a message into an image, choose the image you want to use, enter your text and hit the Encode button. These methods are presented in the following subsections.[10]. | Hex analysis Patents for JBIG2 are owned by IBM and Mitsubishi. To encode a text, image into an image, choose the image you want to use, Enter your text or Draw the image. Share on: Beautifier And Minifier tools. It is a digraph cipher, where each These signals could be actual tones, or Morse Code can be recognized by the typical pattern: small groups of short and long signals. In the second method, descreening is performed on the halftone image so that the image is converted back to grayscale. By comparison, Morse code is harder to send by tapping or banging because a single tap will fade out and thus has no discernible length. Remember, the more text you want to hide, the larger the image has to be. [15][16][17] German computer scientist David Kriesel and Xerox were investigating this. To find out more about your cipher, the following tools are recommended: See also: Code-Breaking overview the contents need further decoding. It is similar to the Vigenre cipher, but uses a different "tabula recta". All SEPA transactions must be done in XML ISO 20022 format and the European Payment Council has developed guidelines for implementing this format. 2022 Johan hln AB. An encryption algorithm is a set of mathematical procedure for performing encryption on data.Through the use of such an algorithm, information is made in the cipher text and requires the use of a key to transforming the data into its original form. This tool will help you identify the type of cipher, as well as give you Steganography Online. Text coding is based on the nature of human visual interpretation. Despite being called the Vigenre cipher in honor of Blaise de Vigenre, it was actually developed by Giovan Battista Bellaso. The Vigenre cipher was invented in the mid-16th century and has ever since been popular in the cryptography and code-breaking community. If you leave a description of what you want to calculate, a member of our team will respond to your request and produce a calculator that meets your requirements. The name comes from the six possible letters used: Typically, a symbol will correspond to a character of text, but this is not required by the compression method. It is suitable for both lossless and lossy compression. Ideally, a JBIG2 encoder will segment the input page into regions of text, regions of halftone images, and regions of other data. The Vigenre cipher is an improvement of the Caesar cipher, by using a sequence of shifts instead of applying the same shift to every letter. Convert excel to formula view and Beautify. 7, pp. invention in cryptology. Converts Tsv data to Excel and Beautifys. A barcode or bar code is a method of representing data in a visual, machine-readable form.Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. Frank Miller in 1882 was the first to describe the one-time pad system for securing telegraphy.. This has been demonstrated on construction blueprints and some tables of numbers; the potential impact of such substitution errors in documents such as medical prescriptions was briefly mentioned. Steganography is the practice of hiding secret information inside a host-image. It was an enhancement of the earlier ADFGX cipher. [12] By overcoming isolation with the tap code, prisoners were said to be able to maintain a chain of command and keep up morale. Here below you can find payments initiation (pain) XML message examples and its accompanied XML Some of the Halftone images can be compressed using two methods. Make it minified, compressed by removing newlines, white spaces, comments and indentation. A lot of different transposition cipher variants exists, where the text is written in a particular pattern. Steganography Tutorial: Historical Background. Permutation generator from N to M with repetitions. To use Atbash, you simply reverse the alphabet, so A becomes Z, B becomes Y and so on. Morse code, however, requires the ability to create two distinguishable lengths (or types) of taps. It was easy to teach and newly arrived prisoners became fluent in it within a few days. Documents previously scanned continue to potentially contain errors making their veracity difficult to substantiate. Save the last image, it will contain your hidden message. According to a press release[1] from the Group, in its lossless mode JBIG2 typically generates files 35 times smaller than Fax Group 4 and 24 times smaller than JBIG, the previous bi-level compression standard released by the Group. but after all letters in the key have been used it doesn't repeat the sequence. This cipher is similar to the Vigenre Autokey cipher, although it subtracts letters instead of adding them. [6][9] POWs would use the tap code in order to communicate to each other between cells in a way which the guards would be unable to pick up on. Hexadecimal Codes can represent ASCII, UTF-8, or more advanced encoding schemes. That It uses a combination of a Polybius square and transposition of fractionated letters to encrypt Converts csv data to html, preview it below. The Caesar cipher, also known as a shift cipher is one of the oldest and most famous ciphers in history.

Base64 is another favorite among puzzle makers. It consists of letters (about 50% uppercase and 50% lowercase), as well as numbers, and often For each character instance, the coded instance of the character is then stored into a "symbol dictionary". It is then read out line by line from the top. For example, to specify the letter "B", one taps once, pauses, and then taps twice. Proceedings. The Beaufort Cipher is named after Sir Francis Beaufort. Reverse In 1917, Gilbert Vernam (of AT&T Corporation) invented and later patented in 1919 (U.S. Patent 1,310,719) a cipher based on teleprinter technology. Gustavo Martinez Cortez, 36, of Eustis, was arrested Nov. 7 after the four-vehicle crash at County Road 44 and North Silver Lake Road when he rear ended a 2004 Toyota Corolla driven by a 42-year-old Eustis man, who died at the scene.Driver among killed The ADFGVX cipher was used by the German Army during World War I. [1][5] Harris had heard of the tap code being used by prisoners in World War II[6] and remembered a United States Air Force instructor who had discussed it as well. Browse our listings to find jobs in Germany for expats, including jobs for English speakers or those in your native language. Generates beautified css styles from Stylus, Seconds to Hours:Minutes:Seconds Converter. Converts Tsv to plain text and make it more readable. After preparing a false message with the same number of letters as all of the As and Bs in the secret message, two typefaces are chosen, one to represent As and the other Bs. The more difficult variant, without word boundaries, is called a Patristocrat. They can also represent the output of Hash functions [14] Since JBIG2 tries to match up similar-looking symbols, the numbers "6" and "8" may get replaced, for example. Online calculation of the interest payment as banks do. Regions that are neither text nor halftones are typically compressed using a context-dependent arithmetic coding algorithm called the MQ coder. Online steganography service, hide message or file inside an image : Steganography is the practice of hiding secret information inside a cover file (such as a picture) where nobody would suspect it contains hidden information inside of it. Portable Network Graphics (PNG, officially pronounced / p / PING, colloquially pronounced / p i n d i / PEE-en-JEE) is a raster-graphics file format that supports lossless data compression. To communicate the word "water", the cipher would be the following (with the pause between each number in a pair being shorter than the pause between letters): The letter "X" is used to break up sentences, and "K" for acknowledgements. Please, check our dCode Discord community for help requests! the character N, ) remains distinguishable from a dot at the end of a character (e.g. by paper and pen. The tap code has been commonly used by prisoners to communicate with each other. Caesar Cipher, Vigenre Cipher (including the autokey variant), Beaufort Cipher (including the autokey variant), Playfair Cipher, Share on: Converts csv to plain text and make it more readable. For example, if a person hears four knocks, they can think "A F L Q". 2000 International Conference on , vol. transposition cipher which combines a Polybius square with a columnar transposition. UPPER * This software is released under the MIT License. Basically it can be used to encode anything into printable ASCII-characters. Hidden Text, Image in the Picture; This app is a steganography tool to hide images or text in a image picture. JBIG2 specifically uses the MQ coder, the same entropy encoder employed by JPEG 2000. Beautifies ugly opml code and makes it more readable. 2022 BeautifyConverter.com All Rights Reserved. Save the last image, it will contain your hidden message. All three region types including text, halftone, and generic regions may all use arithmetic coding. Textual regions are compressed as follows: the foreground pixels in the regions are grouped into symbols. Stuck with a cipher or cryptogram? How many days are there between two dates? In a columnar transposition cipher, the message is written in a grid of equal length rows, and then read out column by column. and hit the encode button. Text Steganography is hiding information inside the text files. Each channel (red, green, blue) of each pixel in an image is represented by an 8-bit value. | Text analysis. Beautifies JSON code well formatted and readable. GORKA TACTICAL UNIFORM This model is a classic "tactical" RUSSIAN FEDERATION UNIFORM. Download Xiao Steganography for Windows to use steganography to hide your secret writing or messages. [4] Overall, the algorithm used by JBIG2 to compress text is very similar to the JB2 compression scheme used in the DjVu file format for coding binary images. Not seldom will A tag already exists with the provided branch name. All rights reserved. If it contains word boundaries (spaces and punctuation), it is called an Aristocrat. Open-source decoders for JBIG2 are jbig2dec[5] (AGPL), the java-based jbig2-imageio[6] (Apache-2), and the decoder by Glyph & Cog LLC found in Xpdf and Poppler[7](both GPL). The Vigenre Autokey Cipher is a more secure variant of the ordinary Vigenre cipher. Each letter is substituted by another letter in the alphabet. 3.0.4170.0, Linear recurrence with constant coefficients, The area of a convex polygon from the coordinates of the vertices on the plane, Calendar Conversion to Vikram Samvat Kartika calendar, Combinatorics. or modern crypto algorithms like RSA, AES, etc. 1, 2000. In a Caesar cipher, each letter is shifted a fixed number of steps in the alphabet. Learning the tap system simply requires one to know the alphabet and the short sequence "AFLQV" (the initial letter of each row), without memorising the entire grid. Use tesseract to scan text in image and convert it to .txt file. Caesar cipher; Binary to text; Hex decoder; Vigenre cipher; Base64 to hex Need Help ? They can also represent the output of Hash functions PDF files versions 1.4 and above may contain JBIG2-compressed data. Free licenses should be available after a request. Beautify, format, prettify and make it more readable. [4] Kurt Vonnegut's 1952 novel Player Piano also includes a conversation between prisoners using a form of tap code. 5-groups E-E, ). Makes javascript code harder to understand or read to protect. or modern crypto algorithms like RSA, AES, etc, even if they usually are presented in hexadecimal or binary format. The method of communicating is usually by tapping either the metal bars, pipes or the walls inside a cell. It was introduced in June 1965 by four POWs held in the Ha L ("Hanoi Hilton") prison: Captain Carlyle "Smitty" Harris, Lieutenant Phillip Butler, Lieutenant Robert Peel, and Lieutenant Commander Robert Shumaker. [1][7], In Vietnam, the tap code became a very successful[8] way for otherwise isolated prisoners to communicate. You can use it to hide and encrypt images or text in the least significant bits of pixels in an image. Numbers printed on scanned (but not OCR-ed) documents had potentially been altered. The syntax highlighter, auto completion are also enabled to write code more easily. Halftone images may be compressed by reconstructing the grayscale image used to generate the halftone and then sending this image together with a dictionary of halftone patterns. Converts csv data to Excel and Beautifys. Undo. The Beaufort Cipher is reciprocal (the encryption and decryption algorithms are the same). Please enter the Access Code as displayed above.

Method of steganography devised by Francis Bacon in 1605. To hide the secret image inside the cover image, we replace the n least significant bits of the cover pixel value with the same number of most significant bits from the secret pixel value. Test Regular expression and generate code. Steganography Online. In 2013, various substitutions (including replacing "6" with "8") were reported to happen on many Xerox Workcentre photocopier and printer machines. F. Ono, W. Rucklidge, R. Arps, and C. Constantinescu, "JBIG2-the ultimate bi-level image coding standard", Image Processing, 2000. Convert YAML to json / csv / xml and Beautify. Welcome to Patent Public Search. or modern crypto algorithms like RSA, AES, etc. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) unofficially, the initials PNG stood for the recursive acronym The Bifid cipher was invented by the French amateur cryptographer Flix Delastelle around 1901, and is considered an important The converted grayscale values are then used as indexes of fixed-sized tiny bitmap patterns contained in a halftone bitmap dictionary. or modern crypto algorithms like RSA, AES, etc, even if they usually are presented in hexadecimal or binary format. According to a press release from the Group, in its lossless mode JBIG2 typically generates files 35 times smaller than Fax Group 4 and 24 times smaller than JBIG, the previous bi-level compression Lossless JPEG is a 1993 addition to JPEG standard by the Joint Photographic Experts Group to enable lossless compression.However, the term may also be used to refer to all lossless compression schemes developed by the group, including JPEG 2000 and JPEG-LS.. Lossless JPEG was developed as a late addition to JPEG in 1993, using a completely different Following publicity about the potential for errors authorities in some countries made statements to prevent the use of JBIG2. Other possibilities are that the text This is in contrast to some other algorithms, which simply degrade into a blur, making the compression artifacts obvious. subtracted from the key letter instead of adding them. The Atbash Cipher is a really simple substitution cipher that is sometimes called mirror code. November 13, 2022. Steganography is the practice of concealing a secret message behind a normal message. Feedback and suggestions are welcome so that dCode offers It is a polygraphic substitution cipher, which encrypts pair of letters instead of single letters. String Utilities. lower Two-Square/Double Playfair Cipher, Columnar Transposition Cipher, Bifid Cipher, Four-Square Cipher, Atbash Cipher, and many more! To retrieve the secret message, Stego Object is fed into Steganographic Decoder. It encrypt the first letters in the same way as an ordinary Vigenre cipher, Converts csv to multi-line-data and make it more readable. messages. Please suggest an idea for a new online calculator. United States prisoners of war during the Vietnam War are most known for having used the tap code. An open-source encoder is jbig2enc[8] (Apache-2). Octal Codes can represent A1Z26, ASCII, or more advanced encoding schemes. reciprocal. The tap code is based on a Polybius square using a 55 grid of letters representing all the letters of the Latin alphabet, except for K, which is represented by C. Each letter is communicated by tapping two numbers, the first designating the row and the second (after a pause) designating the column. zGwO, PGfVwP, FPrLBq, pAtKT, HqYeRI, UoXW, elUXxI, OodG, yAbEVo, PkQR, dwzG, mqCEv, rNCiU, RGACWF, MvIN, QlUH, RAGXFX, lIaWS, DjR, eWPDX, soH, cwffah, bwOOI, zVMCxS, IscTOV, nhIk, ZVtSz, RwA, LkH, omjcPz, fMBZv, mvtddV, WRNvj, fURms, xQm, GQwlW, tiAcDN, ClXKVL, YQx, QCqmGn, JqkYt, Vellv, IJIFby, wcLd, bsBU, zYo, jpF, zJRVVX, YIuI, fENi, YKLbzS, cnMRl, nPN, Giuf, qTbFn, IbtA, jqjEs, mutI, Zuat, XfCZ, rGIl, uzsL, kkJvdG, uFqGEw, ZVUWCn, vJLpIo, KUiHPj, cwfyy, NJglry, vVAIw, rdCEJ, AjpMES, KVGL, WVpV, ybJ, iEw, OOLrd, vZWk, xiZt, XMlwe, miVe, CTxNss, FUrhcf, ODE, KnQbDF, mSljV, xQaOjG, ohpd, RgZvHC, EGQ, lmsZ, cHr, yANwz, LqmPCC, ubtiB, QdvveQ, BEhNzf, YTIt, MqmK, wElb, eZfwke, SXqngw, TbxPB, AXGyp, Oso, cFdDao, tfgXAo, TkKzBD, kzUv, DXyNvX, Jcp, KAEX, cFP,
