Noise-Java Library

Noise-Java is a plain Java implementation of the Noise Protocol, intended as a reference implementation. The code is distributed under the terms of the MIT license.

This library is written in plain Java, making use of the Java Cryptography Extension (JCE) to provide cryptographic primitives and infrastructure. Where a primitive is not normally present in standard JDK's, Noise-Java provides fallback implementations. It is assumed that the platform JDK has the following providers built-in:

• SHA-256
• SHA-512
• AES/GCM/NoPadding

If AES/GCM/NoPadding is not available, then the Noise-Java library will emulate GCM on top of AES/CTR/NoPadding using a custom GHASH implementation. If CTR mode isn't available either, then the "AESGCM" cipher cannot be used.

All other cryptographic primitives are emulated with plain Java reference implementations: ChaChaPoly, BLAKE2s, BLAKE2b, Curve25519, and Curve448.

If you have better implementations of the cryptographic primitives available, you can modify the createDH(), createCipher(), and createHash() functions in the "Noise" class to integrate your versions.

The package documentation contains more information on the classes in the Noise-Java library.
