示例1: createRawSignature
import java.security.Signature; //導入方法依賴的package包/類
public Signature createRawSignature(AlgorithmIdentifier algorithm)
{
Signature sig;
try
{
String algName = getSignatureName(algorithm);
algName = "NONE" + algName.substring(algName.indexOf("WITH"));
sig = helper.createSignature(algName);
// RFC 4056
// When the id-RSASSA-PSS algorithm identifier is used for a signature,
// the AlgorithmIdentifier parameters field MUST contain RSASSA-PSS-params.
if (algorithm.getAlgorithm().equals(PKCSObjectIdentifiers.id_RSASSA_PSS))
{
AlgorithmParameters params = helper.createAlgorithmParameters(algName);
params.init(algorithm.getParameters().toASN1Primitive().getEncoded(), "ASN.1");
PSSParameterSpec spec = (PSSParameterSpec)params.getParameterSpec(PSSParameterSpec.class);
sig.setParameter(spec);
}
}
catch (Exception e)
{
return null;
}
return sig;
}
