The cloud agent supports issuance and presentation of credentials following the . Anoncreds credentials have many privacy-preserving capabilities such as blinded holder bindings, zero-knowledge proofs and selective disclosure.

The cloud agent supports issuance and presentation of W3C credentials following the spec, using LD-Proofs (JSON Linked Data Proofs).

Hyperledger Aries protocols from the AIP1 suite can be used to issue credentials and present proofs. This includes the protocols and respectively.

Hyperledger Aries protocols from the AIP2 suite can also be used to issue credentials and present proofs. This includes the protocols and respectively.

and

The cloud agent establishes DIDComm connections using the AIP1 connection protocol ().

The cloud agent uses the AIP2 basic message protocol for exchanging arbitrary messages along a DIDComm connection ().

The cloud agent supports the issuance of W3C credentials using BBS+ signatures (). This signature allows the holder to selectively disclose a subset of their W3C credential attributes when performing a proof exchange.
