Class SubjectAltPublicKeyInfo

java.lang.Object

org.bouncycastle.asn1.ASN1Object

org.bouncycastle.asn1.x509.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.
