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:

 (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

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.
