+
+DESCRIPTION
+-----------
+Generate a base64-encoded NVMe TLS pre-shared key (PSK).
+The resulting key is either printed in the PSK interchange format
+'NVMeTLSkey-1:01:<base64 encoded data>:' or inserted as a
+'retained' key into the specified keyring if the '--insert' option
+is given.
+When the PSK should be inserted into the keyring a 'retained' key
+is derived from the secret key material. The resulting 'retained'
+key is stored with the identity
+'NVMe0R0<hmac> <host NQN> <subsystem NQN>'
+(for identity version '0') or
+'NVMe1R0<hmac> <host NQN> <subsystem NQN> <PSK hash>'
+(for identity version '1') in the keyring.
+The 'retained' key is derived from the secret key material,
+the specified subsystem NQN, and the host NQN.
+Once the 'retained' key is stored in the keyring the original
+secret key material cannot be retrieved.
+
+OPTIONS
+-------
+-k <name>::
+--keyring=<name>::
+	Name of the keyring into which the 'retained' TLS key should be
+	stored. Default is '.nvme'.
+
+-t <type>::
+--keytype=<type>::
+	Type of the key for resulting TLS key.
+	Default is 'psk'.
+
+-n <nqn>::
+--hostnqn=<nqn>::
+	Host NVMe Qualified Name (NQN) to be used to derive the
+	'retained' TLS key
+
+-c <nqn>::
+--subsysnqn=<nqn>::
+	Subsystem NVMe Qualified Name (NQN) to be used to derive the
+	'retained' TLS key
+
+-h <hmac-id>::
+--hmac=<hmac-id>::
+	Select a HMAC algorithm to use. Possible values are:
+	1 - SHA-256 (default)
+	2 - SHA-384
+
+-I <vers>::
+--identity=<id-vers>::
+	Select the TLS identity to use. Possible values are:
+	0 - Original NVMe TLS 1.0c identity
+	1 - NVMe TLS 2.0 (TP8018) identity
+
+-s <secret>::
+--secret=<secret>::
+	Secret value (in hexadecimal) to be used for the key. If none are
+	provided a random value is used.
+
+-i::
+--insert::
+	Insert the resulting TLS key into the keyring without printing out
+	the key in PSK interchange format.
+
+-o <fmt>::
+--output-format=<fmt>::
+	Set the reporting format to 'normal', 'json' or 'binary'. Only one
+	output format can be used at a time.
+
+-v::
+--verbose::
+	Increase the information detail in the output.
