DESCRIPTION
Takes a NVMe TLS PSK in the PSK interchange format NVMeTLSkey-1:01:<base64-encoded data>:, derives a retained key identity from it and the given host/subsystem NQNs using the HKDF-Expand-Label algorithm from RFC 8446, and stores the result into the specified keyring. The 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). Once the retained key is stored in the keyring the original key material cannot be retrieved.
This command is for deriving a new retained-key identity from raw PSK material; it always needs a subsystem NQN (and, if not given, will look up the host NQN) to compute that identity. If the identity under which a key should be stored is already known — for example a key previously exported by linknvme-keys-export[1], or a KX-HMAC-CHAP secret — use linknvme-keys-import[1] instead, which inserts a key under an explicit identity without deriving one.
If --keydata is not given the key is read from stdin, which also allows inserting a key stored in a file, e.g. nvme keys insert-tls -c <subsysnqn> < keyfile.
To check whether a key is already loaded without inserting it, use linknvme-keys-check-tls[1].
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. Required.
- -d <key>
- --keydata=<key>
-
Key to be inserted. If not given, the key is read from stdin.
- -I <id-vers>
- --identity=<id-vers>
-
NVMe TLS key identity version to be used; 0 for the default identity, and 1 for the TLS identity suffixed by the PSK hash as specified in TP8018.
- -C
- --compat
-
Use the original non-RFC 8446 compliant algorithm when deriving the TLS key for compatibility with older implementations.
- -f <keyfile>
- --keyfile=<keyfile>
-
Append the resulting TLS key to keyfile.
GLOBAL OPTIONS
The following options are defined at the top-level nvme command
and are available to this subcommand:
- --dry-run
-
Print the command that would be executed, but do not actually execute it.
- --no-ioctl-probing
-
Disable probing for 64-bit IOCTL support.
- --no-retries
-
Disable retry logic on transient errors.
- -o <fmt>
- --output-format=<fmt>
-
Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.
- --output-format-version=<version>
-
Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.
- --timeout=<ms>
-
Set the timeout for the command in milliseconds.
- -v
- --verbose
-
Increase the level of detail in the output. May be specified multiple times to further increase verbosity.
These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.
