High-performance cryptography for the JVM

Native implementations of a number of cryptographic primitives using optimized instructions such as AES-NI and PCLMUL available on recent x86-64 CPUs. Specifically this library provides:

* AES in CBC, CTR, and GCM modes
* AES + HMAC-SHA2
* AES + SHA3 (Keccak-MAC)

Additionally included are routines for generating cryptographically secure random bytes via the RDRAND instrution and fast constant-time array comparison using SSE2.

Usage

The goal of this library is to provide secure, high-performance cryptographic primitives using a simple non-JCE interface:

Cipher cipher = Crypto.cipher(AES, CBC, key, iv)
cipher.encrypt(bytes, len)

Authenticated encryption:

Cipher cipher = Crypto.cipher(AES, CBC, key, iv)
cipher.authenticate(SHA2, 256, key)
cipher.encrypt(bytes, len)
byte[] mac = cipher.mac()

Secure random bytes (requires CPU supporting RDRAND):

Crypto.bytes(iv, len)
