All Implemented Interfaces:

ExtendedSignature

public final class RsaPssWithDigestSignature
extends RsaPssSignature

The RSA-PSS signature algorithm implemented with an underlying hash function selected by algorithm parameters.

This implementation calculates the hash internally, thus it is the message itself (being signed or verified) that is passed in through the update() API.

An instance of this algorithm can be obtained using the Java Cryptography Architecture (JCA), by requesting a 'RSAPSS' digital signature from the Entrust cryptographic service provider. This can be done using the following call:

Signature.getInstance("RSAPSS", "Entrust");

FIPS 140-2:

This class is part of the Toolkit's FIPS 140-2 cryptographic module and contains APIs that are considered part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; refer to the API documentation for further details

Constructor Detail

RsaPssWithDigestSignature

public RsaPssWithDigestSignature()

The constructor; creates a new instance of the RSAPSS digital signature algorithm.

Applications should not use this constructor, instead the signature algorithm should be requested from the appropriate JCA/JCE cryptographic service provider as follows: Signature.getInstance("RSAPSS", "Entrust")
