AuthorityKeyIdentifierStructure

public class AuthorityKeyIdentifierStructure extends org.bouncycastle.asn1.x509.AuthorityKeyIdentifier
A high level authority key identifier.

Fields Summary
Constructors Summary
public AuthorityKeyIdentifierStructure(byte[] encodedValue)
Constructor which will take the byte[] returned from getExtensionValue()

param
encodedValue a DER octet encoded string with the extension structure in it.
throws
IOException on parsing errors.

        super((ASN1Sequence)X509ExtensionUtil.fromExtensionValue(encodedValue));
public AuthorityKeyIdentifierStructure(X509Certificate certificate)
Create an AuthorityKeyIdentifier using the passed in certificate's public key, issuer and serial number.

param
certificate the certificate providing the information.
throws
CertificateParsingException if there is a problem processing the certificate

        super(fromCertificate(certificate));
public AuthorityKeyIdentifierStructure(PublicKey pubKey)
Create an AuthorityKeyIdentifier using just the hash of the public key.

param
pubKey the key to generate the hash from.
throws
InvalidKeyException if there is a problem using the key.

        super(fromKey(pubKey));
