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>
