Milan Broz	ba384d15d2	Add optimized Argon2 SSE code. ... Note: it is always better to use external libargon2 library. Unfortunately, until Argon2 is in generic crypto libraries, we must sometimes use bundled version just for bureaucratic reasons. Let's include optimized variant of reference implementation as well. Note, this code will not add any SSE compiler switches. If --enable-internal-sse-argon2 option is used, it checks if current compilation flags support simple SSE progam and if so, it use the optimized variant. (Not tested for AVX optimizations; it expects that SSE is enabled as well.)	2018-07-07 10:36:49 +02:00

Milan Broz	09d14a0b6c	Add Argon2 bundled library to crypto backend. ... The Argon2i/id is a password hashing function that won Password Hashing Competiton. It will be (optionally) used in LUKS2 for passworrd-based key derivation. We have to bundle code for now (similar PBKDF2 years ago) because there is yet no usable implementation in common crypto libraries. (Once there is native implementation, cryptsetup will switch to the crypto library version.) For now, we use reference (not optimized but portable) implementation. This patch contains bundled Argon2 algorithm library copied from https://github.com/P-H-C/phc-winner-argon2 For more info see Password Hashing Competition site: https://password-hashing.net/ and draft of RFC document https://datatracker.ietf.org/doc/draft-irtf-cfrg-argon2/ Signed-off-by: Milan Broz <gmazyland@gmail.com>	2017-08-06 21:13:12 +02:00
