affine cipher

The table below shows the completed table for encrypting a message in the Affine cipher.

The Atbash cipher can be seen as a special case of the affine cipher.

The Caesar cipher is the Affine cipher when since the encrypting function simply reduces to a linear shift.

Since the affine cipher is still a monoalphabetic substitution cipher, it inherits the weaknesses of that class of ciphers.

This generator is not a cryptographically secure pseudorandom number generator for the same reason that the affine cipher is not secure.

The same type of transformation used in affine ciphers is used in linear congruential generators, a type of pseudorandom number generator.

Considering the specific case of encrypting messages in English (i.e. ), there are a total of 286 non-trivial affine ciphers, not counting the 26 trivial Caesar ciphers.

In the past, part A cryptograms have been encrypted with the Caesar cipher, the Affine cipher, the Keyword cipher, the Transposition cipher and the Vigenère cipher.

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.

The 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.

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.

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 to be 5, to be 8, and to be 26 since there are 26 characters in the alphabet being used.
