public class Sha256RSASignature
extends RSASignature

This class implements the RSA PKCS#1v1.5 digital signature algorithm (RSASSA-PKCS1-v1_5) using (SHA256) as message digest algorithm.

The PKCS#1v1.5 "SHA256 with RSA" signature algorithm is described in PKCS#1.

An application wishing to sign some message or to verify some signature using the "SHA256 with RSA" algorithm, generally has to perform three steps:

Constructor Detail

Sha256RSASignature

public Sha256RSASignature()
Default Constructor.

Applications do not call this constructor. They shall use one of the getInstance methods of the java.security.Signature class:

 Signature sig = Signature.getInstance("SHA256withRSA");
