Hello,
I've released a new native OSS crypto library for the JVM that uses
AES-NI, PCLMUL, and RDRAND instructions available on recent x86-64
CPUs:
https://github.com/wg/crypto
It supports AES in CBC, CTR, and GCM modes with optional
authentication, secure random number generation (RDRAND, Ivy Bridge+
CPUs only), and constant-time byte array comparison. I believe the API
is simple and less error prone than the JCE's. However it is designed
as a low level library and requires the user to correctly assemble the
provided primitives.
This is just a hobby project and I am not a cryptographer. I have
however placed an emphasis on testing and it passes all publicly
available NIST AESAVS tests. The underlying AES implementation is
hardware, and the driver code is OSS from Intel and the OpenBSD
project. The GCM wrapper of CTR and GMAC, RDRAND driver, and other
utilities were written by me.
Doubtless I am not looking in the right place, but I do not see the api
for RDRAND - or indeed the api for anything.
The documentation for Rdrand appears to be:
Secure random bytes (requires CPU supporting RDRAND):
Crypto.bytes(iv, len)
Which is less than helpful.
