d812c7209f sha2: import SHA1 implementation 2016-11-05 15:14:37 +01:00

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.
