AuthorityKeyIdentifier

public AuthorityKeyIdentifier(SubjectPublicKeyInfo spki)

Calulates the keyidentifier using a SHA1 hash over the BIT STRING from SubjectPublicKeyInfo as defined in RFC2459. Example of making a AuthorityKeyIdentifier:

   SubjectPublicKeyInfo apki = new SubjectPublicKeyInfo((ASN1Sequence)new DERInputStream(
       new ByteArrayInputStream(publicKey.getEncoded())).readObject());
   AuthorityKeyIdentifier aki = new AuthorityKeyIdentifier(apki);

                              java.math.BigInteger serialNumber)

create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided as well.
