createAuthorityKeyIdentifier

public org.bouncycastle.asn1.x509.AuthorityKeyIdentifier createAuthorityKeyIdentifier(java.security.cert.X509Certificate cert)
                                                                               throws java.security.cert.CertificateEncodingException

createAuthorityKeyIdentifier

public org.bouncycastle.asn1.x509.AuthorityKeyIdentifier createAuthorityKeyIdentifier(java.security.PublicKey pubKey)

createAuthorityKeyIdentifier

public org.bouncycastle.asn1.x509.AuthorityKeyIdentifier createAuthorityKeyIdentifier(java.security.PublicKey pubKey,
                                                                                      org.bouncycastle.asn1.x509.GeneralNames generalNames,

createSubjectKeyIdentifier

public org.bouncycastle.asn1.x509.SubjectKeyIdentifier createSubjectKeyIdentifier(java.security.PublicKey publicKey)
Return a RFC 3280 type 1 key identifier. As in: (1) The keyIdentifier is composed of the 160-bit SHA-1 hash of the value of the BIT STRING subjectPublicKey (excluding the tag, length, and number of unused bits).
Parameters:
publicKey - the key object containing the key identifier is to be based on.
Returns:
the key identifier.

createTruncatedSubjectKeyIdentifier

public org.bouncycastle.asn1.x509.SubjectKeyIdentifier createTruncatedSubjectKeyIdentifier(java.security.PublicKey publicKey)
Return a RFC 3280 type 2 key identifier. As in: (2) The keyIdentifier is composed of a four bit type field with the value 0100 followed by the least significant 60 bits of the SHA-1 hash of the value of the BIT STRING subjectPublicKey.
Parameters:
publicKey - the key object of interest.
Returns:
the key identifier.

parseExtensionValue

public static org.bouncycastle.asn1.ASN1Primitive parseExtensionValue(byte[] encExtValue)
                                                               throws java.io.IOException
Return the ASN.1 object contained in a byte[] returned by a getExtensionValue() call.
Parameters:
encExtValue - DER encoded OCTET STRING containing the DER encoded extension object.
Returns:
an ASN.1 object
Throws:
java.io.IOException - on a parsing error.
