Jochen Hoenicke	32bda8d1d9	Faster PBKDF2 by reusing intermediate results. ... The old implementation needed 6 sha transformations per iterations: - 2 for computing sha512 of seed, - 2 for computing digests of ipads/opads, - 2 for computing digests of intermediate hashes. The first 4 transformations are the same in every iteration so we cache them. A new function hmac_sha512_prepare computes these digests. We made sha512_Transform visible in pbkdf2 and prevent unneccessary big/little endian conversions back and forth.	2016-07-13 22:17:23 +02:00
