                           throws CertificateEncodingException

Return the encoded form of this certificate.

Returns:

The encoded form.

Throws:

Verifies the signature of this certificate.

Parameters:

key - The signer's public key.

Throws:

CertificateException

NoSuchAlgorithmException - If the algorithm used to sign the certificate is not available.

InvalidKeyException - If the supplied key is not appropriate for the certificate's signature algorithm.

NoSuchProviderException

SignatureException - If the signature could not be verified.

verify

public abstract void verify(PublicKey key,
          String sigProvider)
                     throws CertificateException,
                            NoSuchAlgorithmException,

Verifies the signature of this certificate, using the specified security provider.

Parameters:

key - The signer's public key.

sigProvider - The name of the signature provider.

Throws:

CertificateException

NoSuchAlgorithmException - If the algorithm used to sign the certificate is not available.
