Adding BLAKE2S as a hash

[ronwa...@gmail.com]

Hi -

I want to use the BLAKE2S (https://blake2.net/) hash within the TomCrypt structure.

Unfortunately, I don't see a way to add my (previously unknown to TC) hash without modifying TC code, particularly the "hash_state" structure.

Am I missing something?   I don't want to make my own modifications to TC unless it's really necessary.

Thanks!

Hi,

as the BLAKE2 sources are CC0 licensed we could simply integrate BLAKE2
in ltc. (Patches/Pull Requests welcome)

Otherwise you could somehow modify the BLAKE2 sources to fit the ltc
structures and create your own structs for ltc_hash_descriptor and
hash_state ... and after some nasty typecasts you should be able to
register the BLAKE2 descriptor and use BLAKE2 as if it were built into
ltc...

I'd prefer the way to integrate it into ltc... also it'd be somehow the
same effort without the need to do these nasty typecasts...

Thanks!  Of course, I long ago integrated BLAKE2s (and 2b) into 8th.  But I'm looking forward to the official next release of tomcrypt!
