InfoThe affine cipher is a type of monoalphabetic substitution cipher, wherein each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter.more...The formula used means that each letter encrypts to one other letter, and back again, meaning the cipher is essentially a standard substitution cipher with a rule governing which letter goes to which. As such, it has the weaknesses of all substitution ciphers.

In this example, the encrypted text would be IHHWVCSWFRCP.The table below shows the completed table for encrypting a message in the Affine cipher.In this decryption example, the ciphertext that will be decrypted is the ciphertext from the encryption example.…

However, this may not have been an issue in the cipher's time.The Atbash cipher can be seen as a special case of the affine cipher.…

The same type of transformation used in affine ciphers is used in linear congruential generators, a type of pseudorandom number generator.This generator is not a cryptographically secure pseudorandom number generator for the same reason that the affine cipher is not secure.In these two examples, one encrypting and one decrypting, the alphabet is going to be the letters A through Z, and will have the corresponding values found in the following table.…

Since the affine cipher is still a monoalphabetic substitution cipher, it inherits the weaknesses of that class of ciphers.The Affine cipher is a Caesar cipher when a=1 since the encrypting function simply reduces to a linear shift.…

They also must not be used for cryptographic applications; see cryptographically secure pseudo-random number generator for more suitable generators.If a linear congruential generator is seeded with a character and then iterated once, the result is a simple classical cipher called an affine cipher; this cipher is easily broken by standard frequency analysis.…

In these two examples, one encrypting and one decrypting, the alphabet is going to be the letters A through Z, and will have the corresponding values found in the following table.In this encrypting example, the plaintext to be encrypted is "AFFINE CIPHER" using the table mentioned above for the numeric values of each letter, taking a to be 5, b to be 8, and m to be 26 since there are 26 characters in the alphabet being used.Only the value of a has a restriction since it has to be coprime with 26.…

The game was played by members of 4chan's music imageboard, which hosted threads to discuss the progress and new findings of the game.The game employed many types of encryption through image, text and sound files, including Braille, QR code, Base64, the Caesar cipher, Binary code, Morse code and the Affine cipher, and used websites such as Imgur and various TOR related sites.The game yielded the first mention of the original release date of No Love Deep Web, October 23, 2012, and an unmastered version of The Money Store for download on the first day.…
