TSIK and customized JCE povider

["Santhanakrishnan, Gopikrishna" <gs...@verisign.com>]

Hi,
 
I have a question on TSIK and JCE provider customization within JSSE.
If I want to use IBMJCE implementation programmatically within Sun JRE
to sign xml using TSIK like follows:
 
KeyFactory keyFactory = KeyFactory.getInstance("RSA", "IBMJCE");

PrivateKey privateKey = keyFactory.generatePrivate(privKeySpec);
CertificateFactory certFactory = CertificateFactory.getInstance("X.509",
"IBMJCE");
Certificate
cert=(X509Certificate)certFactory.generateCertificate(certStream);
...
//TSIK  API 
Signer signer = new Signer(applicationXML, privateKey, cert);
..
signer.sign(..);
 
Unlike JSSE API calls for PrivateKey and Certificate,  TSIK API for
Signer is not taking the custom JCE provider name in its call.  How am I
sure that TSIK is using IBMJCE hash implementation and NOT the default
SunJCE hash implemenatation?
 
Thanks
Gopi
