.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 -v
produces more verbose output, in particular providing a few
bits of feedback to help the user detect mistyping.
.PP
Option
.B -c
prompts for a password change.
.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 default file read by
.IR factotum (4)
at startup, open a new window and 
.sp
.EX
  % ramfs -p; cd /tmp
  % auth/secstore -g factotum
  secstore password:
  % echo 'key proto=apop dom=x.com user=ehg !password=y~1' >> factotum
  % auth/secstore -p factotum
  secstore password:
  % read -m factotum > /mnt/factotum/ctl
.EE
and delete the window.
The first line 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
.I Aescbc
encrypts and decrypts using AES (Rijndael) in cipher
block chaining (CBC) mode.  This is the file encryption
used internally by
.IR secstore .

.IR secstore (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.
