X509Certificate.getSigAlgParams

Gets the DER-encoded signature algorithm parameters from this certificate's signature algorithm. In most cases, the signature algorithm parameters are null; the parameters are usually supplied with the certificate's key. If access to individual parameter values is needed then use {@link java.security.AlgorithmParameters AlgorithmParameters} and instantiate with the name returned by {@link #getSigAlgName() getSigAlgName}.

<p>See {@link #getSigAlgName() getSigAlgName} for relevant ASN.1 definitions.

@return the DER-encoded signature algorithm parameters, or null if no parameters are present.
