    • getApplyingSubpacket

      protected OpenPGPSignature.OpenPGPSignatureSubpacket getApplyingSubpacket(Date evaluationTime, int subpacketType)
      Return the SignatureSubpacket instance of the given subpacketType, which currently applies to the key. Since subpackets from the Direct-Key signature apply to all subkeys of a certificate, this method first inspects the signature that immediately applies to this key (e.g. a subkey-binding signature), and - if the queried subpacket is found in there, returns that instance. Otherwise, indirectly applying signatures (e.g. Direct-Key signatures) are queried. That way, preferences from the direct-key signature are considered, but per-key overwrites take precedence.
      Parameters:
      evaluationTime - evaluation time
      subpacketType - subpacket type that is being searched for
      Returns:
      subpacket from directly or indirectly applying signature
