Affine Cipher
The Affine cipher is a type of substitution cipher rooted in modular arithmetic, which falls under the category of monoalphabetic ciphers. It has origins in classical cryptography, dating back to the use of basic substitution techniques by ancient civilizations.
A1Z26 Cipher
The A1Z26 cipher, also known as the letter-number cipher or the alphabet cipher, is a simple substitution cipher where each letter of the alphabet is replaced with its corresponding position number.
In the A1Z26 cipher:
The letter A is represented by the number 1.
The letter B is represented by the number 2.
The letter C is represented by the number 3.
