abstract val keyPair: KeyPairAdapter

The public key for this agent, i.e. the public part of the key that signs issued credentials.

Functions

abstract fun buildRevocationList(timePeriod: Int? = null): String?

Returns a Base64-encoded, zlib-compressed bitstring of revoked credentials, where the entry at "revocationListIndex" (of the credential) is true iff it is revoked

abstract suspend fun issueCredential(subjectPublicKey: CryptoPublicKey, credentialScheme: ConstantIndex.CredentialScheme, representation: ConstantIndex.CredentialRepresentation, claimNames: Collection<String>? = null, dataProviderOverride: IssuerCredentialDataProvider? = null): KmmResult<Issuer.IssuedCredential>

Issues credentials for some credentialScheme to the subject specified with its public key in subjectPublicKey in the format specified by representation. Callers may optionally define some attribute names from ConstantIndex.CredentialScheme.claimNames in claimNames to request only some claims (if supported by the representation).

abstract suspend fun issueRevocationListCredential(timePeriod: Int? = null): String?

Wraps the revocation information into a VC, returns a JWS representation of that.

Link copied to clipboard
abstract fun revokeCredentials(credentialsToRevoke: List<String>): Boolean

Revokes all verifiable credentials from credentialsToRevoke list that parse and validate. It returns true if all revocations was successful.

Link copied to clipboard
abstract fun revokeCredentialsWithId(credentialIdsToRevoke: Map<String, Instant>): Boolean

Revokes all verifiable credentials with ids and issuance date from credentialIdsToRevoke It returns true if all revocations was successful.
