Hi All,
I am installed/created the keystore file with Signature algorithm name: SHA256withRSA . But getting the below error from IDP side.
Caused by: java.security.SignatureException: Signature encoding error

at sun.security.rsa.RSASignature.engineVerify(RSASignature.java:195)
That is due to the below lines in org.picketlink.identity.federation.core.saml.v2.util.SignatureUtil class getSignature() method
if ("DSA".equalsIgnoreCase(algo)) {
sig = Signature.getInstance(PicketLinkFederationConstants.DSA_SIGNATURE_ALGORITHM);
} else if ("RSA".equalsIgnoreCase(algo)) {
sig = Signature.getInstance(PicketLinkFederationConstants.RSA_SIGNATURE_ALGORITHM); //SHA1withRSA
}
Because as I explained earlier I have created the keystore with SHA256withRSA so the keyalg RSA. But the above code is setting the Signature as SHA1withRSA even though it is SHA256withRSA.
Can you please fix this ASAP if possible. We got stuck up due to this.
Regards,
Vinay
