gnutls_hpke_export(3) gnutls gnutls_hpke_export(3) NAME gnutls_hpke_export - API function SYNOPSIS #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); ARGUMENTS 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 ex- port. 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. DESCRIPTION This function performs the export operation of HPKE. It derives a se- cret of length bytes from the exporter secret in the HPKE context, us- ing 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 ex- porter 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 re- sponsible for freeing this memory using gnutls_free() when it is no longer needed.
