.SH "NAME"
nvme-keys-export \- Export NVMe TLS PSKs from a keyring
.SH "SYNOPSIS"
.sp
.nf
\fInvme\fR [<global\-options>] \fIkeys export\fR [\-\-keyring=<name> | \-k <name>]
                        [\-\-keyfile=<file> | \-f <file>]
.fi
.SH "DESCRIPTION"
.sp
Export all NVMe TLS pre\-shared keys (PSKs) from the system keyring in the form
.sp
<description> <psk>
.sp
where \fI<description>\fR is the key description from the exported key and \fI<psk>\fR is the key data in PSK interchange format \fINVMeTLSkey\-1:01:<base64 encoded data>:\fR\&. Each key is exported in a single line\&.
.SH "OPTIONS"
.PP
\-k <name>, \-\-keyring=<name>
.RS 4
Name of the keyring to export the retained keys from\&. Default is
\fI\&.nvme\fR\&.
.RE
.PP
\-f <file>, \-\-keyfile=<file>
.RS 4
File to write the exported keys to instead of stdout\&.
.RE
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
