Class X500Signer

java.lang.Object
org.mozilla.jss.netscape.security.x509.X500Signer

public final class X500Signer extends Object
This class provides a binding between a Signature object and an authenticated X.500 name (from an X.509 certificate chain), which is needed in many public key signing applications.

The name of the signer is important, both because knowing it is the whole point of the signature, and because the associated X.509 certificate is always used to verify the signature.

The X.509 certificate chain is temporarily not associated with the signer, but this omission will be resolved.

    • update

      public void update(byte[] buf, int offset, int len) throws SignatureException
      Called for each chunk of the data being signed. That is, you can present the data in many chunks, so that it doesn't need to be in a single sequential buffer.
      Parameters:
      buf - buffer holding the next chunk of the data to be signed
      offset - starting point of to-be-signed data
      len - how many bytes of data are to be signed
      Throws:
      SignatureException - on errors.
    • sign

      public byte[] sign() throws SignatureException
      Produces the signature for the data processed by update().
      Throws:
      SignatureException - on errors.
    • getAlgorithmId

      public AlgorithmId getAlgorithmId()
      Returns the algorithm used to sign.
    • getSigner

      public X500Name getSigner()
      Returns the name of the signing agent.
