Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, Bo-Yin Yang. + +It is "ref10" implementation from the SUPERCOP: +https://bench.cr.yp.to/supercop.html + +OpenSSH also uses ed25519 from SUPERCOP, but "ref" implementation. + +There are four ed25519 implementations in SUPERCOP, ref10 is faster then ref, +and there are two that are even faster, written in amd64 assembler. +Benchmarks are here: https://bench.cr.yp.to/impl-sign/ed25519.html + +============================== +MariaDB changes: + +API functions were simplified to better fit our use case: +* crypto_sign_open() does not return the verified message, only the + result of the verification (passed/failed) +* no secret key is generated explicitly, user specified password is used + as a source of randomness instead (SHA512("user password")). +* lengths are not returned, where they're known in advance + (e.g. from crypto_sign()). +* crypto_sign() does not take the public key as an argument, but + generates it on the fly (we used to generate public key before + crypto_sign(), doing it internally avoids double work). + +See the changes done in this commit. |
