NVME-GEN-TLS-KEY(1)               NVMe Manual              NVME-GEN-TLS-KEY(1)

NAME
       nvme-gen-tls-key - Generate a NVMe TLS PSK (deprecated)

SYNOPSIS
       nvme [<global-options>] gen-tls-key [--keyring=<name> | -k <name>]
                               [--keytype=<type> | -t <type>]
                               [--hostnqn=<nqn> | -n <nqn>]
                               [--subsysnqn=<nqn> | -c <nqn>]
                               [--hmac=<hmac-id> | -m <hmac-id>]
                               [--identity=<id-vers> | -I <id-vers>]
                               [--secret=<secret> | -s <secret>]
                               [--insert | -i]
                               [--compat | -C]
                               [--keyfile=<keyfile> | -f <keyfile>]

DESCRIPTION
       Deprecated alias for nvme-keys-gen-tls-psk(1), kept for scripts written
       against nvme-cli versions older than 3.0, with three differences from
       nvme-cli 2.x:

       o   --insert/-i reports Inserted TLS PSK <serial> where 2.x said
           Inserted TLS key <serial>. A script matching the old wording needs
           updating.

       o   A --secret with an odd number of hexadecimal characters is
           rejected. 2.x padded the trailing character with a zero and emitted
           a secret that was never given, the same behaviour nvme-gen-dhchap-
           key(1) had.

       o   The diagnostics that validate --secret go to stdout, where 2.x put
           them on stderr. Most of them accompany a non-zero exit, but
           Skipping excess secret bytes does not: an over-long --secret still
           exits 0, with the warning sitting on stdout ahead of the key, so a
           script reading the key off stdout gets the warning instead.

       New scripts should use nvme keys gen-tls-psk instead. This alias prints
       a deprecation warning on stderr and may be removed in a future release.

       See nvme-keys-gen-tls-psk(1) for the full option reference.

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.
