If you take a look at the source code for
org.mozilla.jss.provider.java.security.JSSSignatureSpi
you can see how does JSS use private key for signing, basically:
CryptoToken owningToken = privKeyByCert.getOwningToken();
Signature signatureContext =
owningToken.getSignatureContext(SignatureAlgorithm.RSASignatureWithSHA1Digest);
signatureContext.initSign(privKeyByCert);
byte[] clearText = "tosign".getBytes();
signatureContext.update(clearText);
byte[] signedBytes = signatureContext.sign();
