Crack legacy zip encryption with Biham and Kocher's known plaintext attack.

Go implementation of the Data At Rest Encryption (DARE) format.

One-time encrypted password/secret sharing

Scripts that illustrate basic cryptography concepts based on Coursera Standford Cryptography I course and more.

Tool and library for cracking legacy zip files.

AES cryptographic library for .NET Framework and .NET Core

Example of AWS Key Management Service encrypt/decrypt in ruby

Cryptanalysis library for breaking classical ciphers

Two scripts in Python to encrypt/decrypt using the 128 bits AES algorithm, ECB mode with hex "00" as padding for each character. For the encryption, an ascii plaintext file is taken as the input, then an encrypted hex file is outputted. For the decryption, a ciphertext hex file is taken as the input, then a decrypted ascii file is outputted.

An OpenCL implementation of most common ciphers

A python code that performs a Vigenere cipher. Do both encryption of a plain text or decryption for a cipher text. in Vigenere cipher the key used in encryption or decryption is a single word and the message contains characters only.
