DES、AES、Present、Extended Euclidean Algorithm、Miller-Rabin（ 常用密码学算法）推荐书籍《现代密码学趣味之旅》---彭长根

Official CrypTool 2 (CT2) repository. CT2 is an open-source software for learning about cryptography and cryptanalysis interactively. CT2 provides a comprehensive suite of tools to deeply explore algorithms and protocols, making it perfect for both academic study and personal exploration. It also includes features for analyzing historical ciphers.

Symmetric encryption and decryption in Ruby with OpenSSL

This project presents a Visual Studio solution including a simple demo ASP.Net Web API Basic Authentication Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the Web API with CRUD operations (GET, POST, PUT, DELETE) that service design requires authentication (except the Get). In addition to demonstrating standard CRUD capabilities, the Web API service implements a .Net Memory Cache (MemoryCache) and custom username and password validator. Passwords are stored securely using Password-Based Key Derivation Function PBKD cryptology. The client “tester” windows form application is not intended as a UX/UI demo but used to test and verify that the backend authentication service allows the user to register with a username and password and verify the Web API CRUD functions based on basic authentication scheme. Lastly, the project is shown in the demo section with a video and screen captures. Note: Every Web API Authentication service should use secure transport. For brevity, this demo project does not implement or discuss the complicated detail nature of SSL/TLS.

PRESENT is a lightweight block cipher.
