A secure chat between an Android client and Java server using AES for encryption and Diffie-Hellman for key exchange.

Encryption And Decryption Using Different Symmetric And Asymmetric Algorithms.

Very simple library based on FramedTCP that provides a fairly secure ecnrypted TCP connection.

A demonstration of a server-client authentication system over TCP using RSA and TEA encryption.

Java Library To Provide Cryptographic Functions

Secure API for Library Management : This API provides a secure solution for managing library operations. It enables users to perform actions such as checking out and returning books, while ensuring data integrity and privacy. Administrators can manage library inventory, handle user accounts, and oversee borrowing activities. Enhanced security featu

Java Implementation of cryptographic program such as encryption, decryption, signature verification, hash.

End to End Encryption between Client to Client interaction through Server using combination of asymmetric and symmetric key encryption

A simple library for easier hash and crypt management. I needed this for a university project.

An attempt to overcome factorization attack on RSA.
