Subject: [PATCH 0/4] Add daemon support for SHA3 and BLAKE2s
Date: Tue, 23 Jun 2020 17:36:33 +0200

Hello!

This is a followup to:

  https://issues.guix.gnu.org/41382

This patch series adds daemon support for a few more cryptographic
hash functions, for use by fixed-output derivations (origins) and
the likes.  We should wait for a year or so before using those
algorithms in package definitions so we can assume that the new
daemon is widespread.

Note that there are still places where SHA256 is hard-coded.
For instance, the ‘query-path-hash’ RPC always returns a SHA256
hash.  Internally, the ‘ValidPaths’ table of the database can
store any hash, but in practice it only ever contains a SHA256
hash (see ‘LocalStore::addValidPath’ and (guix store database)).

Feedback welcome!

Ludo’.

Ludovic Courtès (4):
  daemon: Map directly to gcrypt hash functions.
  daemon: Remove OpenSSL hash compatibility wrappers.
  daemon: Recognize SHA3 and BLAKE2s.
  packages: Recognize SHA3 and BLAKE2s for 'content-hash'.
