All Implemented Interfaces:

ExtendedSignature

public final class RawSslRsaSignature
extends RsaSignature

The RSA-PKCS1-v1_5 signature algorithm with NONE as the underlying hash function.

This implementation DOES NOT calculate the hash internally. It requires that the formatted message hash be passed in through the update() API. This means that the message hash must be calculated externally. This provides the flexibility of allowing the RSA-PKCS1-v1_5 signature algorithm to be used with any underlying hash function.

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

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

Constructor Detail

RawSslRsaSignature

public RawSslRsaSignature()

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

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("NONEwithRSA", "Entrust")
