Version bump and synchronize packages
Uses "dleq-serai", instead of "dleq", as the dleq crate name hasn't been 
transferred yet :(

Enable no_std on transcript
Removes the Vec challenge for an associated type.

Fixes the merlin feature which was horribly broken.

Also adds no_std to dalek-ff-group.

Rename transcript-trait to flexible-transcript
It offers the trait for flexibility, yet it also offers an incredibly 
competent (and logical) transcript format, along with a Merlin wrapper.

Version bump Transcript trait
Preparation for yanking 0.1.0 which had an insecure format due to lack 
of length prefixing labels.

Have DigestTranscript require a 32-byte hash
Needed to generate RNG seeds without panicking. Mandates at least a 
128-bit security level.

Have DigestTranscript update its digest instead of maintaining a Vec 2022-06-24 18:43:32 -04:00

Fix DigestTranscript to be secure
Collisions were possible depending on static label substrings. Now, 
labels are prefixed by their length to prevent this from being possible. 
All variables are also flagged by their type, preventing other potential 
conflicts.

Use a transcript when generating the per-chain binding for a given set of keys
While it was fine as-is, as it only had one variable length property, 
this is a bit more robust. Also binds the Curve ID, which should declare 
differently even for just different basepoints, and therefore adds two 
variable length properties (justifying the transcript).

Remove rng_seed's additional entropy
It was never used as we derive entropy via the other fields in the 
transcript, and explicitly add fields directly as needed for entropy.

Also drops an unused crate and corrects a bug in FROST's Schnorr 
implementation which used the Group's generator, instead of the Curve's.

Also updates the Monero crate's description.

Transcript crate with both a merlin backend and a basic label len value backend
Moves binding factor/seeded RNGs over to the transcripts.
