# [NAME](#NAME)

gnutls\_psk\_format\_imported\_identity - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/gnutls.h>**

**int gnutls\_psk\_format\_imported\_identity(const gnutls\_datum\_t * identity, const gnutls\_datum\_t * context, gnutls\_protocol\_t version, gnutls\_digest\_algorithm\_t hash, gnutls\_datum\_t * imported\_identity);**

# [ARGUMENTS](#ARGUMENTS)

[const gnutls\_datum\_t * identity](#const)

external identity

[const gnutls\_datum\_t * context](#const~2)

optional contextual information

[gnutls\_protocol\_t version](#gnutls_protocol_t)

protocol version to which the PSK is imported

[gnutls\_digest\_algorithm\_t hash](#gnutls_digest_algorithm_t)

hash algorithm used for KDF

[gnutls\_datum\_t * imported\_identity](#gnutls_datum_t)

where the imported identity is stored

# [DESCRIPTION](#DESCRIPTION)

This formats an external PSK identity *identity* into an imported form, described in RFC 9258 as ImportedIdentity.

Upon success, the data field of *imported\_identity* is allocated using **gnutls\_malloc()** and the caller must free the memory after use.

# [RETURNS](#RETURNS)

**GNUTLS\_E\_SUCCESS** (0) on success, otherwise a negative error code.
