<tt>Hello,</tt><br>

I'm working on development of OpenSSL ENGINE that
integrates<br>
post-quantum algorithms (new NIDs). During integration I<br>
need to modify OpenSSL code to add custom function, but
would<br>
prefer not to need add anything to OpenSSL code (so engine<br>
can be dynmicaly loaded by any modern OpenSSL).<br>
</tt></p>
<p><tt>So, In three cases, namely when the code is in
callbacks for keygen,<br>
encryption and ctrl (called by EVP_PKEY_CTX_ctrl,
EVP_PKEY_encrypt <br>
and EVP_PKEY_keygen) I need to get NID of the scheme. The
problem<br>
is that, those functions are called with EVP_PKEY_CTX
object<br>
provided as an argument. The NID is stored in the <br>
</tt><tt>EVP_PKEY_CTX->pmeth->pkey_id. I think (AFAIK)
there is no API<br>
which would return that value.<br>
<br>
I've added a simple function that returns pkey_id from the
ctx, but<br>
that means that I need to change OpenSSL code. Is there
any way<br>
to get NID without changing OpenSSL?<br>
<br>
Kind regards,<br>
