CredentialProtocol

public protocol CredentialProtocol : AnyObject, Sendable

A cryptographic credential.

This is tied to a particular client via either its client id or certificate bundle, depending on its credential type, but is independent of any client instance or storage.

To attach a credential to a client instance and store it, call add_credential on a CoreCryptoContext.

  • Get the earliest possible validity of this credential, expressed as seconds after the unix epoch.

    Basic credentials have no defined earliest validity and will always return 0.

    Declaration

    Swift

    func earliestValidity() -> UInt64

  • Export a PEM string containing the public portion of this credential.

    • Basic credentials export their public key.
    • x509 credentials export the full certificate chain. This enables external tools such as openssl to validate the certificate chain.

    Declaration

    Swift

    func exportPem() -> String

  • Get the signature scheme of this credential.

    Declaration

    Swift

    func signatureScheme() -> SignatureScheme

  • Get the type of this credential.

    Declaration

    Swift

    func type() -> CredentialType
