.SH DESCRIPTION
.PP
.I Secstore
authenticates to the server
using a password and optionally a hardware token,
then saves or retrieves a file.
This is intended to be a credentials store (public/private keypairs,
passwords, and other secrets) for a factotum.
.PP
Option
.B -p
stores a file on the secstore.
.PP
Option
.B -g
retrieves a file to the local directory;
option
.B -G
writes it to standard output instead.
Specifying
.I getfile
of . will send to standard output
a list of remote files with dates, lengths and SHA1 hashes.
.PP
Option
.B -r
removes a file from the secstore.
.PP
Option
.B -c
prompts for a password change.
.PP
Option
.B -v
produces more verbose output, in particular providing a few
bits of feedback to help the user detect mistyping.
.PP
Option
.B -i
says that the password should be read from standard input
instead of from
.BR /dev/cons .
.PP
Option
.B -n
says that the password should be read from NVRAM
instead of from
.BR /dev/cons .
This option is unsupported.
.PP
The server is
.BR tcp!$auth!5356 ,
or the server specified by option
.BR -s .
.PP
For example, to add a secret to the file read by
.IR factotum (4)
at startup, open a new window, type
.sp
.EX
% ramfs -p; cd /tmp
% auth/secstore -g factotum
secstore password:
% echo 'key proto=apop dom=x.com user=ehg !password=hi' >> factotum
% auth/secstore -p factotum
secstore password:
% read -m factotum > /mnt/factotum/ctl
.EE
.PP
and delete the window.
The first line creates an ephemeral memory-resident workspace,
invisible to others and automatically removed when the window is deleted.
The next three commands fetch the persistent copy of the secrets,
append a new secret,
and save the updated file back to secstore.
The final command loads the new secret into the running factotum.
.\" .PP
.\" The
.\" .I ipso
.\" command packages this sequence into a convenient script to simplify editing of
.\" .I files
.\" stored on a secure store.
.\" It copies the named
.\" .I files
.\" into a local
.\" .IR ramfs (4)
.\" and invokes
.\" .IR acme (1)
.\" on them. When the editor exits,
.\" .I ipso
.\" prompts the user to confirm copying modifed or newly created files back to
.\" .I secstore.
.\" If no
.\" .I file
.\" is mentioned,
.\" .I ipso
.\" grabs all the user's files from
.\" .I secstore
.\" for editing.
.\" .PP
.\" By default, ipso will edit the
.\" .I secstore
.\" files and, if
.\" one of them is named
.\" .BR factotum ,
.\" flush your current keys from factotum and load
.\" the new ones from the file.
.\" If you supply any of the
.\" .BR -e ,
.\" .BR -f ,
.\" or
.\" .BR -l
.\" options,
.\" .I ipso
.\" will just perform the operations you requested, i.e.,
.\" edit, flush, and/or load.
.\" .PP
.\" The
.\" .B -s
.\" option of
.\" .I ipso
.\" invokes
.\" .IR sam (1)
.\" as the editor insted of
.\" .BR acme ;
.\" the
.\" .B -a
.\" option provides a similar service for files encrypted by
.\" .I aescbc
.\" .RI ( q.v. ).
.\" With the
.\" .B -a
.\" option, the full rooted pathname of the
.\" .I file
.\" must be specified and all
.\" .I files
.\" must be encrypted with the same key.
.\" Also with
.\" .BR -a ,
.\" newly created files are ignored.
.PP
.I Aescbc
encrypts and decrypts using AES (Rijndael) in cipher
block chaining (CBC) mode.
.SH SOURCE
.B \*9/src/cmd/secstore
.SH SEE ALSO
.IR factotum (4),
Plan 9's \fIsecstore\fR(8)
.SH BUGS
There is deliberately no backup of files on the secstore, so
.B -r
(or a disk crash) is irrevocable. You are advised to store
important secrets in a second location.
.\" .PP
.\" When using
.\" .IR ipso ,
.\" secrets will appear as plain text in the editor window,
.\" so use the command in private.
