> This is a first stab at preparing for a possible migration to
> hash algorithms other than SHA256 (there’s no rush AFAIK, but it’s
> good to be prepared).  The first bits just improve tests and
> adjust the tools, which doesn’t hurt.
>
> The last bit adds a ‘sha512’ field to <origin>, which we could
> eventually provide instead of or in addition to ‘sha256’, possibly
> as a base64-encoded string so that it’s not too large.
>
> Another option would be to create a <hash> data type that specifies
> its algorithm and its value.  We’d replace the ‘sha256’ field with
> a ‘hash’ field of that type (in a backward-compatible way).  Thinking
> about it, this is perhaps the better option.

> Other bits that would need to be adjusted include importer, updaters,
> and ‘guix publish’.
