Cipher-Algorithms and some hacks to (some of) them

Some Cryptographic Algorithms written in python3

Basic implementations of well-known cryptographic ciphers and attacks on these ciphers.

Demonstration of some attacks exploiting security vulnerabilities of websites and OSs as tasks of Computer Security LAB, CSE 406 in Level-4, Term-1 of CSE, BUET

This is an symmetric encryption algorithm. It is a more glorified version of a substitution cipher. However, some substitutions are added that do not correspond to a letter to try and confuse anyone trying to break the cipher

Classical Encryption/Substitution Cipher Example

implementation de quelques techniques de chiffrement

Program that encrypts plaintext and (attempts) to decrypt ciphertexts, encrypted via a mono-alphabetic substitution cipher. Replaces letters based on frequency / n-gram analysis. Tried to incorporate hill-climbing algorithm by measuring the fitness of resulting texts to find the best key.

Implimentation of Extended Substitution Cipher

A substitution - permutation cipher using a symmetric key

This repository implements a variety of cryptographic methods and methods of breaking them

poor man's homophonic substitution cipher

Encryption/Decryption (Substitution Cipher)

A demonstration project for cryptography concepts

This is an implementation of all famous cryptography algorithms in python. There are several algorithm of cipher in this like Caesar, Transposition, Substitution, Vigenere, AES and RSA

A script for decrypting text encrypted with monoalphabetic/simple substitution ciphers using combined pattern deduction.

A tool to Encrypt, Decrypt & Crack texts with a substitution cipher

The Al Bhed are a tribe of technologists in Final Fantasy X and Final Fantasy X-2. Making up ten percent of the Spiran population, they have a unique language and, unlike the other races in Spira, use machina (technology).
