Class AuthorityKeyIdentifierExtension

java.lang.Object

com.tencent.kona.sun.security.x509.Extension

com.tencent.kona.sun.security.x509.AuthorityKeyIdentifierExtension

All Implemented Interfaces:

com.tencent.kona.sun.security.util.DerEncoder, java.security.cert.Extension

public class AuthorityKeyIdentifierExtension
extends Extension

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

Constructor Detail

AuthorityKeyIdentifierExtension

public AuthorityKeyIdentifierExtension(KeyIdentifier kid,
                                       GeneralNames names,
                                       SerialNumber sn)

The default constructor for this extension. At least one parameter must be non null. Null parameters make the element optional (not present).

Parameters:

kid - the KeyIdentifier associated with this extension.

names - the GeneralNames associated with this extension

sn - the CertificateSerialNumber associated with this extension.

AuthorityKeyIdentifierExtension

public AuthorityKeyIdentifierExtension(java.lang.Boolean critical,
                                       java.lang.Object value)
                                throws java.io.IOException

Create the extension from the passed DER encoded value of the same.

Parameters:

critical - true if the extension is to be treated as critical.

value - an array of DER encoded bytes of the actual value.

Throws:

java.lang.ClassCastException - if value is not an array of bytes

java.io.IOException - on error.
