SignedCertificateTimestamp

data class SignedCertificateTimestamp(val version: SctVersion, val logId: LogId, val timestamp: Instant, val extensions: ByteArray, val signature: DigitallySigned, val origin: Origin)(source)

A Signed Certificate Timestamp (SCT) as defined in RFC 6962 §3.2.

An SCT is a promise from a CT log that a certificate (or precertificate) has been logged. It contains the log's identity, a timestamp, and a digital signature that can be verified against the log's public key.

SCTs can be delivered via three mechanisms, indicated by origin:

  • Embedded in the certificate's X.509 extensions

  • Via TLS extension during the handshake

  • Via OCSP stapled response
