Class SubjectAltPublicKeyInfo

  • All Implemented Interfaces:
    ASN1Encodable, Encodable
    public class SubjectAltPublicKeyInfo
extends ASN1Object
    X.509 Section 9.8.2.
    This public-key certificate extension, when present, shall contain the subject’s alternative public key information 
     subjectAltPublicKeyInfo EXTENSION ::= {
      SYNTAX SubjectAltPublicKeyInfo
      IDENTIFIED BY id-ce-subjectAltPublicKeyInfo }

 SubjectAltPublicKeyInfo ::= SEQUENCE {
     algorithm AlgorithmIdentifier{{SupportedAlgorithms}},
     subjectAltPublicKey BIT STRING }
    The SubjectAltPublicKeyInfo data type has the following components:
    • the algorithm subcomponent, which shall hold the algorithm that this public key is an instance of
    • the subjectAltPublicKey subcomponent, which shall hold the alternative public key
    This extension may be flagged as critical or as non-critical.
    NOTE – It is recommended that it be flagged as non-critical. Flagging it as critical would require relying parties to understand this extension and the alternative public-key algorithm.
