Thanks a lot for your reply, i thought the problem was either when i
generated the hash or when i sign it. The problem with the CcMethods
documentation is that .... i made that class :P
this is the code for the signing method:
// Signs given hash
public static byte[] sign(byte[] hash){
try {
KeyStore ks = builder.getKeyStore();
Key key = ks.getKey(aliasCertifLabel, null);
CK_MECHANISM mechanism = new CK_MECHANISM();
mechanism.mechanism = PKCS11Constants.CKM_RSA_PKCS;
mechanism.pParameter = null;
Signature sig =
Signature.getInstance("SHA1withRSA",ks.getProvider());
sig.initSign((PrivateKey)key) ;
sig.update(hash);
return sig.sign();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
this seemed quite simple and since i get asked for the digital signature pin
and i see the certificate inside the pdf document, i assumed everything was
working well.
Do you see anything wrong with this?
Regards,
Pedro
