A becomes N, B becomes O, and so on up to M, which becomes Z, then the sequence continues at the beginning of the alphabet: N becomes A, O becomes B, and so on to Z, which becomes M.Only those letters which occur in the English alphabet are affected; numbers, symbols, whitespace, and all other characters are left unchanged.
This number comes from the fact there are 12 numbers that are coprime with 26 that are less than 26 (these are the possible values of a).
The first letter is replaced with the last letter, the second with the second-last, and so on.
An example plaintext to ciphertext using Atbash: a AAAAA g AABBA m ABABB s BAAAB y BABBA b AAAAB h AABBB n ABBAA t BAABA z BABBB c AAABA i ABAAA o ABBAB u BAABB d AAABB j BBBAA p ABBBA v BBBAB e AABAA k ABAAB q ABBBB w BABAA f AABAB l ABABA r BAAAA x BABAB In the affine cipher the letters of an alphabet of size m are first mapped to the integers in the range 0..m - 1.
It can be shown as follows that decryption function is the inverse of the encryption function, Read more ...
Applying ROT13 to a piece of text merely requires examining its alphabetic characters and replacing each one by the letter 13 places further along in the alphabet, wrapping back to the beginning if necessary.
