Java实现的DH算法，包括API端和客户端的所有实现

Encrypts messages between parties using RSA/DH for key exchange and AES for encryption

Enigma is a Java-based cryptographic system that integrates symmetric (AES, DES, Blowfish), asymmetric (Diffie-Hellman, RSA, DSA), and hashing algorithms (MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512). It ensures data confidentiality, integrity, and authentication with modern cryptographic standards.

Diffie-Hellman key exchange and Bruteforce

Artifacts for the "Fooling primality tests on smartcards" paper at ESORICS 2020

In this repository we want to apply encryption algorithms such as rsa, sha256 and diffhelman and how they help us protect our messages.

Implementation of Diffie-Hellman Key-exchange, RSA algorithm, DSS(Digital Signature Signing and Verification), Extended Euclidean Algo., Fermat's Little Theorem, Fast Modular Exponentiation

A java text editor and email client for public key cryptography and encryption. The ciphers use hypercomplex and hyper-dimensional numbers (including vectors, quaternions, matrices, cubes, and tesseracts), polynomials, determinants, multi-variable, multi-equation, and multi-dimensional arithmetic, and Merkle-Hellman knapsacks.
