Digital Signature Protocol

Overview

Project contains implementation of digital signature protocol based on ElGamal cryptosystem.

Componetns

All functionality are duplicated: use long for maximum performance and BigInteger for variable key leanght and maximum security.

As cryptographic hash function was built hash function based on Merkle-Damgard scheme with a Misty cipher as the main component. As a digital signature algorithm El-Gamal system that uses modular arithmetic was used.

For application execution was created CLI that gives possibility to sign any file with creating additional metadata.
