gnutls_hpke_derive_keypair(3) gnutls gnutls_hpke_derive_keypair(3)
gnutls_hpke_derive_keypair - API function
#include <gnutls/hpke.h>
int gnutls_hpke_derive_keypair(gnutls_hpke_kem_t kem, const
gnutls_datum_t * ikm, gnutls_privkey_t privkey, gnutls_pubkey_t
pubkey);
gnutls_hpke_kem_t kem
The KEM algorithm to use for key pair generation.
const gnutls_datum_t * ikm
A pointer to a gnutls_datum_t structure containing the
input key material (IKM) to be used for key pair
generation.
gnutls_privkey_t privkey
An initialized private key.
gnutls_pubkey_t pubkey
An initialized public key.
This function derives a key pair (private key and public key) for
the specified KEM algorithm from the provided input key material (
ikm ).
ikm is used as a seed for the key generation process, allowing
for deterministic key pair generation if the same IKM is used. The
function checks that the provided parameters are valid and that
the KEM algorithm is supported.
ikm should be a non-empty byte string that serves as the seed for
key pair generation.
0 on success, or a negative error code on failure
