Juan Carrano	62667848c4	sys/hashes/pbkdf2: Add PBKDF2-sha256 implementation. This add an implementation of PBKDF2 using sha256 hmac. Only one derived key length is supported (32) though it should not be hard to extend it. The testing is done with both random (with fixed seed) vectors amd vectors from rfc7914.	2020-11-04 09:57:32 +01:00

sys/hashes/pbkdf2: wipe local variables, prevents leaks.
