# [DESCRIPTION](#DESCRIPTION)

Deprecated alias for [**nvme-keys-gen-tls-psk**(1)](/man/os/nvme-cli/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:

•*--insert*/*-i* reports *Inserted TLS PSK &lt;serial&gt;* where 2.x said *Inserted TLS key &lt;serial&gt;*. A script matching the old wording needs updating.

•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)](/man/os/nvme-cli/nvme-gen-dhchap-key.1) had.

•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)](/man/os/nvme-cli/nvme-keys-gen-tls-psk.1) for the full option reference.

# [GLOBAL OPTIONS](#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 &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

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=&lt;ms&gt;

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)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.
