gnutls_hpke_init - API function

NAME SYNOPSIS ARGUMENTS DESCRIPTION RETURNS SINCE REPORTING BUGS COPYRIGHT SEE ALSO

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);

ARGUMENTS

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).

DESCRIPTION

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.

RETURNS

0 on success, or a negative error code on failure
