libnvmf_generate_tls_key_identity_compat-libnvme32
Generate the tls psk identity
Usage
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 |
Overview
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.
