.SH "DESCRIPTION"
.sp
The Security Send command is used to transfer security protocol data to the controller\&. The data structure transferred to the controller as part of this command contains security protocol specific commands to be performed by the controller\&. The data structure transferred may also contain data or parameters associated with the security protocol commands\&. Status and data that is to be returned to the host for the security protocol commands submitted by a Security Send command are retrieved with the Security Receive command\&.
.sp
The association between a Security Send command and subsequent Security Receive command is Security Protocol field dependent as defined in SPC\-4\&.
.SH "OPTIONS"
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
Target a specific namespace for this security command\&.
.RE
.PP
\-N <nssf>, \-\-nssf=<nssf>
.RS 4
NVMe Security Specific field\&. If using security protocol EAh assigned for NVMe use, the NVMe security specific field indicates which reply memory buffer target\&.
.RE
.PP
\-f <file>, \-\-file=<file>
.RS 4
Path to file used as the security protocol\(cqs payload\&. Required argument\&.
.RE
.PP
\-p <security\-protocol>, \-\-secp=<security\-protocol>
.RS 4
Security Protocol: This field specifies the security protocol as defined in SPC\-4\&. The controller shall fail the command with Invalid Parameter indicated if a reserved value of the Security Protocol is specified\&.
.RE
.PP
\-s <security\-protocol\-specific>, \-\-spsp=<security\-protocol\-specific>
.RS 4
SP Specific: The value of this field is specific to the Security Protocol as defined in SPC\-4\&.
.RE
.PP
\-t <trans\-length>, \-\-tl=<trans\-length>
.RS 4
Transfer Length: The value of this field is specific to the Security Protocol as defined in SPC\-4\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR
or
\fIbinary\fR\&. Only one output format can be used at a time\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the information detail in the output\&.
.RE
.PP
\-\-timeout=<timeout>
.RS 4
Override default timeout value\&. In milliseconds\&.
