# [NAME](#NAME)

nvme-keys-export - Export NVMe TLS PSKs from a keyring

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] keys export [--keyring=<name> | -k <name>]


                        [--keyfile=<file> | -f <file>]
```

# [DESCRIPTION](#DESCRIPTION)

Export all NVMe TLS pre-shared keys (PSKs) from the system keyring in the form

&lt;identity&gt; &lt;psk&gt;

where *&lt;identity&gt;* is the TLS PSK identity the key is stored under and *&lt;psk&gt;* is the TLS PSK itself in PSK interchange format *NVMeTLSkey-1:&lt;hmac&gt;:&lt;base64 encoded data&gt;:*. Each key is exported in a single line.

The PSK interchange format otherwise carries a configured PSK: it is what [**nvme-keys-gen-tls-psk**(1)](/man/os/nvme-cli/nvme-keys-gen-tls-psk.1) prints and what [**nvme-keys-insert-tls-psk**(1)](/man/os/nvme-cli/nvme-keys-insert-tls-psk.1) and [**nvme-keys-check-tls-psk**(1)](/man/os/nvme-cli/nvme-keys-check-tls-psk.1) read. The keys exported here are TLS PSKs instead. This output is meant for [**nvme-keys-import**(1)](/man/os/nvme-cli/nvme-keys-import.1), which stores each key back under its identity unchanged; it is not intended to be passed to [**nvme-keys-insert-tls-psk**(1)](/man/os/nvme-cli/nvme-keys-insert-tls-psk.1) or [**nvme-keys-check-tls-psk**(1)](/man/os/nvme-cli/nvme-keys-check-tls-psk.1).

# [OPTIONS](#OPTIONS)

-k &lt;name&gt;, --keyring=&lt;name&gt;

Name of the keyring to export the TLS PSKs from. Default is *.nvme*.

-f &lt;file&gt;, --keyfile=&lt;file&gt;

File to write the exported keys to instead of stdout.

# [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. Other versions are rejected.

--quiet

Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

--set-options=&lt;key=value&gt;\[,&lt;key=value&gt;...]

Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

-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.

# [EXAMPLES](#EXAMPLES)

•Export previously created keys from the kernel keyring and store them into a file

```
# nvme keys export -f nvme-tls-keys.txt
```

•Export/list all keys from the .nvme keyring using nvme and keyctl

```
# nvme keys export
NVMe0R01 hostnqn0 subsys0 NVMeTLSkey-1:01:/b9tVz2OXJVISnoFgrPAygyS86XYJWkAapQeULns6PMpM8wv:
# keyctl show
