Flexible Transcript
Flexible Transcript is a crate offering:
Transcript, a trait offering functions transcripts should implement.DigestTranscript, a competent transcript format instantiated against a provided hash function.MerlinTranscript, a wrapper ofmerlininto the trait (available via themerlinfeature).RecommendedTranscript, a transcript recommended for usage in applications. Currently, this isDigestTranscript<Blake2b512>(available via therecommendedfeature).
The trait was created while working on an IETF draft which defined an incredibly
simple transcript format. Extensions of the protocol would quickly require a
more competent format, yet implementing the one specified was mandatory to meet
the specification. Accordingly, the library implementing the draft defined an
IetfTranscript, dropping labels and not allowing successive challenges, yet
thanks to the trait, allowed protocols building on top to provide their own
transcript format as needed.
DigestTranscript takes in any hash function implementing Digest, offering a
secure transcript format around it. All items are prefixed by a flag, denoting
their type, and their length.
MerlinTranscript was used to justify the API, and if any issues existed with
DigestTranscript, enable a fallback. It was also meant as a way to be
compatible with existing Rust projects using merlin.
This library was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing.
This library is usable under no_std.
