Simple cipher contains simple implementations of cryptography and cryptoanalysis on Caesar's Cipher, Vigenere's Cipher, and One Time Pads.

A simple and fast Vigenère solver using Index of Coincidence, Friedman and Chi-squared

Two cipher algorithms developed in C language as part of my studies : Xor and Cbc.

In this endeavor, I've delved into the intricate world of cryptographic puzzles, taking on the challenge of deciphering a unique fusion cipher that incorporates elements of both simple shift and columnar transposition techniques. The goal? To unlock hidden messages and understand the artistry behind secure communication methods.
