gnutls_hpke_export - API function
#include <gnutls/hpke.h>
int gnutls_hpke_export(gnutls_hpke_context_t ctx, const
gnutls_datum_t * exporter_context, size_t length, gnutls_datum_t *
secret);
gnutls_hpke_context_t ctx
The HPKE context to use for exporting the secret.
const gnutls_datum_t * exporter_context
The application-specific context to be included in the
export.
size_t length
The requested length in bytes of the secret to be
exported.
gnutls_datum_t * secret
A pointer to a gnutls_datum_t structure where the
exported secret will be stored.
This function performs the export operation of HPKE. It derives a
secret of length bytes from the exporter secret in the HPKE
context, using the provided application-specific context and the
KDF specified in the context. The resulting secret is stored in
secret . The function checks that the provided parameters are
valid and that the context is properly initialized and that there
is an exporter secret available in the context.
length should be a positive integer that does not exceed the
maximum allowed size for HPKE exports.
The function will allocate memory for secret , and the caller is
responsible for freeing this memory using gnutls_free() when it is
no longer needed.
0 on success, or a negative error code on failure
