NAME
libnvmf_generate_tls_key_identity_compat - Generate the TLS PSK identity
SYNOPSIS
int libnvmf_generate_tls_key_identity_compat (struct libnvme_global_ctx *ctx , const char *hostnqn , const char *subsysnqn , int version , enum libnvmf_hmac_alg hmac , unsigned char *configured_key , int key_len , char **identity );
ARGUMENTS
- ctx
-
struct libnvme_global_ctx object
- hostnqn
-
Host NVMe Qualified Name
- subsysnqn
-
Subsystem NVMe Qualified Name
- version
-
TLS PSK identity version to use
- hmac
-
HMAC algorithm
- configured_key
-
Configured PSK to derive the retained PSK from
- key_len
-
Length of configured_key
- identity
-
TLS PSK identity to return
DESCRIPTION
Derives a retained PSK as specified in the NVMe TCP Transport Specification 1.3, section 3.6.1.3, and generates the corresponding TLS PSK identity. This function differs from libnvmf_generate_tls_key_identity in that it uses the original implementation for HKDF-Expand-Label which does not prefix the 'info' and 'label' strings with the length.
It is the responsibility of the caller to free the returned string.
RETURN
0 on success, negative error code otherwise.
