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

RSA encryption and decryption app with JavaFX GUI

Twofish ECB block cipher implementation in pure Java. No dependencies.

Playfair Cipher Encryption and Decryption - implemented in Java

Cryptography Primitives examples

EncryptionThe Hybrid Caesar Cipher Encryption System is a Java-based encryption tool that extends the classic Caesar cipher by incorporating multiple scrambling, shuffling, and shifting algorithms. This hybrid approach enhances the security of the encryption process.

Secure Chat Application that supports multi multi group conversations and files upload with secure channels based on TLS protocol, management of cryptographic keys and the generation of secure syntheses, ciphers and digital signatures
