Bbs Scheme

[mikelodder7]

Adds BBS signature scheme and abstracts the signature scheme to be pluggable.

Looks like we need to update the rust version

Hey @mikelodder7 — a couple of questions, only one relevant to the merge:

• are all of the AnonCreds v2 ZK features supported? Same as PS?
• Revocation? Is that impacted, or is it still the same.
• I tried to look for tests and I see some that are BBS, but not sure. Are all of the tests run for both PS and BBS signatures?

It’s the last one that is relevant to the PR. The others are documentation :-)

This is awesome to see!

Yes they are swappable.

• Revocation? Is that impacted, or is it still the same.

Revocation works the same regardless of which one is used.

• I tried to look for tests and I see some that are BBS, but not sure. Are all of the tests run for both PS and BBS signatures?

You see some used in flow.rs and other places. They both still work no matter which scheme is used.
