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

<description> <psk>

where <description> is the key description from the exported key and <psk> is the key data in PSK interchange format NVMeTLSkey-1:01:<base64 encoded data>:. Each key is exported in a single line.

OPTIONS

-k <name>, --keyring=<name>

Name of the keyring to export the retained keys 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

•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
