Releases · hyperledger/indy-shared-rs

This release switches the backend for indy-credx from ursa (which is now archived) to the new anoncreds-clsignatures package.

There are relatively minor breaking changes to the API:

MasterSecret is renamed to LinkSecret.
Creating a revocable credential no longer requires a tails file.
Updating a revocation registry requires the credential definition and revocation private key, instead of the tails file.

There are also important security fixes:

For issuers, new revocation registries must be created due to changes to the tails file contents. Credentials should be re-issued.
For provers, the proof of non-revocation has been updated. This means that verifiers that have not been upgraded will not be able to verify the new proof.
For verifiers, a new FFI method is added to verify either the older non-revocation proof format or the new proof format. This is only added to allow for a more gradual upgrade of the ecosystem, and will be removed in a future version.

Performance is generally improved, especially for operations such as creating a new revocation registry.
