Igor created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1793



Hello, dear colleagues!

Are there any plans for support GOST2012 with elliptic curve id-tc26-gost-3410-2012-256-paramSet as discribed in RFC9558?

There is the comment in lib/x509/key_encode.c:

```c
    /* For compatibility per R 1323565.1.023—2018 provide digest OID only
     * for GOST-2001 keys or GOST-2012 keys with CryptoPro curves. Do not
     * set this optional parameter for TC26 curves */
```

But the document has been greatly updated and for now elliptic curves from TC26 are used, for example, in openssl. Or maybe this is a question of nettle software patching?

Thank you in advence for your answer!
