This project collects classic ciphers with high performance implementations.

C# implementation of Speck cipher

C# wrapper implementation of simon-speck-c that is SIMON and SPECK lightweight block ciphers.

Crystalline Cipher 1, 2, 3 & 4 - A set of symmetric ciphers designed to resist attacks by quantum computers.

Implementations of some well known ciphers and algorithms in C# and Java

Desktop application for encrypting text and files using simple substitution and permutation ciphers

Custom symmetric cipher library that I am just building to play with different ways of manipulating data.

Simple console app that encode/decode given string (in future encoding content in .txt file). App is using simple ciphers, cipher list below.

The solution done by me in C# on the challenge "Rail Fence Cipher: Encoding and Decoding" over at www.codewars.com

The program for demonstrating ciphers

A tool for automated solving of messages encrypted with one of 25+ classical ciphers.

EDREJ 1.5 - is the encoder, using the RPB1-Cipher from ZerZru

A C# library for plain text encryption and decryption for simple, but fun ciphers.

C# Project that implements contemporary and retro ciphers where you can enter a key, encrypt and decrypt
