hostnqn

Host NVMe Qualified Name

subsysnqn

Subsystem NVMe Qualified Name

version

Key version to use

hmac

HMAC algorithm

configured_key

Configured key data to derive the key from

key_len

Length of configured_key

Derives a 'retained' TLS key as specified in NVMe TCP and generate the corresponding TLs identity. This version differs from nvme_generate_tls_key_identity in that it uses the original implementation for HKDF-Expand-Label which does not prefix the 'info' and 'label' string with the length.

The string containing the TLS identity. It is the responsibility of the caller to free the returned string.
