Class AbstractX509KeyIdentifier

java.lang.Object
  anon.crypto.AbstractX509Extension
      anon.crypto.AbstractX509KeyIdentifier

Direct Known Subclasses:

X509AuthorityKeyIdentifier, X509SubjectKeyIdentifier

public abstract class AbstractX509KeyIdentifier
extends AbstractX509Extension

The key identifier is calculated using a SHA1 hash over the BIT STRING from SubjectPublicKeyInfo as defined in RFC3280. For DSA-PublicKeys the AlgorithmIdentifier of the SubjectPublicKeyInfo MUST contain the DSA-Parameters as specified in RFC 3279
