Credential signing

The README says the issuer supports the did:key and did:web DID formats for signing keys.Read 4 Oct 2026 · github.com

Credential status

Its optional revocation and suspension mechanism implements Bitstring Status List and stores status lists through database or Git services.Read 11 Oct 2026 · github.com

Endpoint security

Tenant endpoints can require a Bearer token, and the README suggests IP filtering; setting a tenant token to UNPROTECTED leaves its endpoint unprotected.Read 11 Oct 2026 · github.com

Issuing API

It implements the VC-API POST endpoints /credentials/issue and /credentials/status.Read 11 Oct 2026 · github.com

Key support

The issuer supports did:key and did:web key formats, and the README recommends did:web for many production deployments because keys can be rotated without updating credentials signed with old keys.Read 11 Oct 2026 · github.com

Multiple issuers

Tenants allow different signing keys and DIDs to be used for different credentialing purposes.Read 11 Oct 2026 · github.com

Production guidance

The README warns that the shared default signing key is only for testing and evaluation, and says issuers must generate and keep their own signing key private for real credentials.Read 11 Oct 2026 · github.com

Revocation and suspension

Optional status management implements Bitstring Status List and can store status lists using database or Git services.Read 4 Oct 2026 · github.com

Security guidance

The README warns that the shared test signing key is unsafe for real credentials and recommends configuring a private key and suggests IP filtering for issuer endpoints.Read 4 Oct 2026 · github.com

Setup time

The project says its four-step quick start should take less than five minutes.Read 4 Oct 2026 · github.com

Status storage limit

The README recommends database-backed status storage for production and testing, and Git-backed storage only for light testing or experiments.Read 11 Oct 2026 · github.com

Support and contribution
