gnutls_privkey_derive_secret: new function
This adds a new function gnutls_privkey_derive_secret, which can be used in conjunction with the other key import or key generation API to calculate shared secret.
Key import can be done with gnutls_{pubkey,privkey}_import_ecc_raw
for
ECDH and gnutls_{pubkey,privkey}_import_dh_raw
for FFDH, while key
generation could be done with gnutls_privkey_generate2
with respective
algorithms (e.g., GNUTLS_PK_ECDH_X25519
) and key generation parameters
in gnutls_keygen_data_st format.
