NVME-KEYS-EXPORT(1)               NVMe Manual              NVME-KEYS-EXPORT(1)

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

SYNOPSIS
       nvme [<global-options>] keys export [--keyring=<name> | -k <name>]
                               [--keyfile=<file> | -f <file>]

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

       <identity> <psk>

       where <identity> is the TLS PSK identity the key is stored under and
       <psk> is the TLS PSK itself in PSK interchange format
       NVMeTLSkey-1:<hmac>:<base64 encoded data>:. 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) prints and what nvme-keys-insert-tls-
       psk(1) and nvme-keys-check-tls-psk(1) read. The keys exported here are
       TLS PSKs instead. This output is meant for 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) or nvme-keys-check-tls-
       psk(1).

OPTIONS
       -k <name>, --keyring=<name>
           Name of the keyring to export the TLS PSKs from. Default is .nvme.

       -f <file>, --keyfile=<file>
           File to write the exported keys to instead of stdout.

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.

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

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

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

               # nvme keys export
