## What is Affine Cipher?

as **Wikipedia** says: The affine cipher is a type of monoalphabetic substitution cipher, where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter.

* look at the entire article from here: https://en.wikipedia.org/wiki/Affine_cipher

## Formula

```

  C = (a * P + b) mod 26

  P = (a ^ -1 * (C - b)) mod 26

```

## Guide

```

 ! Usage: python3 affinecipher.py    

  

* type    : {e: encryption, d: decryption}

* string  : the text you want to encrypt or decrypt

* a       : the first operand of the key

* b       : the second operand of the key

```
