Affine Cipher Encryption Function Analysis by Jayati Thakkar is a document available to read on EtoBox.
A chosen plaintext attack was performed on an affine cipher using the plaintext "hahaha" and ciphertext "NONONO". By setting up a system of congruences relating the plaintext and ciphertext letters, the encryption function y = 11x + 14 (mod 26) was determined. The inverse of 7 modulo 26 is 15, which allowed the cipher
