A Java implementation of public-key asymmetric Elliptic Curve Cryptography arithmetic to facilitate Eliptic Curve Deffie-Hellmann key exchange, and to issue and verify digital signatures using ECDSA.

JECC: Java Elliptic Curve Cryptography

A Java implementation of public-key asymmetric Elliptic Curve Cryptography point arithmetic to facilitate Eliptic Curve Deffie-Hellmann key exchange, and to issue and verify digital signatures using ECDSA.

Beta Release

As this project is still in beta, there is no intention to make future release backwards compatible.

Implemented Elliptic Curves

Currently, only the secp256k1 curve is implemented.

Instructions

To compute a scalar point multiplication, invoke the scalarMultiply method found within the EcPointArithmetic class.

Testing

The project is extensively tested using automatically generated test vectors from the BouncyCastle library.
