gnutls_hpke_init - API function
#include <gnutls/hpke.h>
int gnutls_hpke_init(gnutls_hpke_context_t * ctx,
gnutls_hpke_mode_t mode, gnutls_hpke_role_t role,
gnutls_hpke_kem_t kem, gnutls_hpke_kdf_t kdf, gnutls_hpke_aead_t
aead);
gnutls_hpke_context_t * ctx
A pointer to the HPKE context to initialize.
gnutls_hpke_mode_t mode
The HPKE mode to use (Base, PSK, Auth, or AuthPSK).
gnutls_hpke_role_t role
The role of the context (Sender or Receiver).
gnutls_hpke_kem_t kem
The KEM algorithm to use (e.g., DHKEM(X25519)).
gnutls_hpke_kdf_t kdf
The KDF algorithm to use (e.g., HKDF-SHA256).
gnutls_hpke_aead_t aead
The AEAD algorithm to use (e.g., AES-128-GCM).
This function initializes the HPKE context with the specified
parameters. It allocates memory for the context and sets the
initial values for the fields based on the provided parameters.
The context must be deinitialized using gnutls_hpke_deinit() when
it is no longer needed to free any allocated resources and
securely erase sensitive information.
