# py-cipher

A few common tools for classical cipher cracking, implemented in Python 3 and C. Uses fogleman's TWL06

### Prerequisites

- Python 3 interpeter

- C compiler

### Setting up

- Compile the C library (example with gcc):

```bash

$ gcc -Ofast -fPIC -shared -o src/libhill.so src/hillmodule.c

```

- Run the graphical interface:

```bash

$ python3 main.py

```

### Supported ciphers

- Affine ciphers (which includes Caesar shifts and Atbash ciphers)

- All monoalphabetic ciphers as long as the word spacing is consistent with the plaintext

- Vigenere ciphers - including vigenere on top of a monoalphabetic cipher

- Hill ciphers with matrix size up to 4x4
