David Woodhouse commented:

I made extra coffee this morning with the intention of writing some RSA-PSS padding code, but I don't see how to do that with an external privkey at all. All the things that _gnutls_pkcs11_privkey_sign() puts into its `rsa_pss_params` come from arguments that privkey_sign_raw_data() doesn't even *pass* to my ->sign_hash_func().

If you expect me to do the padding for myself, how do I know the params?
