This is a library for the OpenID for Verifiable Credentials (OpenID4VC) specifications family developed by the OpenID Digital Credentials Protocols Working Group.
The Digital Credentials Protocols (DCP) Working Group focuses on creating OpenID specifications for a model where issuers provide digital credentials to holders, allowing holders to present them to verifiers. These digital credentials contain cryptographically signed statements about the holder, and verifiers can check their authenticity. The primary goals include enhancing user control and privacy over identity information, making identity verification more efficient and secure, and establishing a universal approach for identification, authentication, and authorization in both digital and physical spaces.
An overview of all the specifications developed by the OpenID Digital Credentials Protocols Working Group can be found here.
