All Implemented Interfaces:
Serializable, CertAttrSet
public class AuthorityKeyIdentifierExtension extends Extension implements CertAttrSet
This class represents the Authority Key Identifier Extension.

The authority key identifier extension provides a means of identifying the particular public key used to sign a certificate. This extension would be used where an issuer has multiple signing keys (either due to multiple concurrent key pairs or due to changeover).

The ASN.1 syntax for this is: 

 AuthorityKeyIdentifier ::= SEQUENCE {
    keyIdentifier             [0] KeyIdentifier           OPTIONAL,
    authorityCertIssuer       [1] GeneralNames            OPTIONAL,
    authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL
 }
 KeyIdentifier ::= OCTET STRING
Version:
1.9
