# nvme\_generate\_tls\_key\_identity(2)

Generate the TLS key identity

## NAME

nvme\_generate\_tls\_key\_identity - Generate the TLS key identity

## SYNOPSIS

**char \* nvme\_generate\_tls\_key\_identity** **(const char \*hostnqn** *,* **const char \*subsysnqn** *,* **int version** *,* **int hmac** *,* **unsigned char \*configured\_key** *,* **int key\_len** *);*

## ARGUMENTS

- 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
