1. Examples


1. Affine Cipher encoder

Text : ABCD efghi
Slope (A) : 3
Intercept (B) : 5
Alphabet : abcdefghijklmnopqrstuvwxyz

Solution:
The Affine cipher is a cipher, where each letter of plaintext is mapped to its numeric equivalent and then encrypted using a linear function y=(ax+b) mod m and then converted back to a letter.

Alphabet = abcdefghijklmnopqrstuvwxyz

2. Affine Cipher encoder

Text : hello world
Slope (A) : 3
Intercept (B) : 5
