This plugin uses public domain ed25519 code
|
|
by Daniel J. 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).
