Verifiable Credentials

One of the main features of Credo is the issuance and verification of Verifiable Credentials.

W3C Verifiable Credentials

W3C Verifiable Credentials are probably the most widely known credential format, and defined the World Wide Web Consortium (W3C).

Credo currently supports the issuance and verification of W3C Verifiable Credentials according to the Data Model v1.1, and support both the Linked Data Proof and Json Web Token (JWT) proof formats.

Issuance of W3C JWT credentials is not supported over DIDComm, while verification is supported

SD-JWT VC

Selective Disclosure JWT Verifiable Credentials are a special type of JWT Verifiable Credentials, that allow for selective disclosure of the claims in the credential.

Credo currently supports SD-JWT-based Verifiable Credentials (SD-JWT VC) - Draft 01.

Issuance of SD-JWT credentials is not supported over DIDComm, while verification is supported.

AnonCreds

Credo supports the issuance and verification of AnonCreds credentials. AnonCreds credentials are a bit 'heavier' to implement and support than other credential formats, but allow for the best unlinkability.

Issuance and verification of AnonCreds credentials is only available over DIDComm.
