public class RsaPssSignature
extends java.security.SignatureSpi

RsaPssSignature implements SignatureSpi and is inherited by specific transformation implementations. The digest mechanism is determined by these subclasses.

This class may be used directly by calling Signature.setParameter(AlgorithmParameterSpec) with a PSSParameterSpec. Otherwise, one of the subclasses of RsaPssSignature may be used. Each subclass sets a default salt length for a given digest.

Since:

5.5.0

Constructor Detail

RsaPssSignature

public RsaPssSignature(CloudHsmProvider provider)

Constructs an empty RsaPssSignature.

A call to Signature::setParameter() is necessary to set the salt length and digest mechanism before this mechanism can be used to generate signatures.

Parameters:

provider - CloudHSM provider offering this service.

See Also:

Signature.setParameter(AlgorithmParameterSpec)

RsaPssSignature

public RsaPssSignature(com.amazonaws.cloudhsm.jce.jni.DigestMechanism digestMechanism,
                       CloudHsmProvider provider)

Construct an RsaPssSignature with a digest mechanism.

A default salt length will be configured equal to the length of the corresponding digest in bytes. A call to Signature::setParameter() is not needed, but can optionally be called to change the default configuration.

Parameters:

digestMechanism - The digest mechanism used to digest the input data.

provider - CloudHSM provider offering this service.
