.TH SECSTORE 1 .SH NAME aescbc, ipso, secstore \- secstore commands .SH SYNOPSIS .B auth/secstore [ .B -cinv ] [ .B -(g|G) .I getfile ] [ .B -p .I putfile ] [ .B -r .I rmfile ] [ .B -s .I server ] [ .B -u .I user ] .PP .B auth/aescbc -e [ -in ] .I <cleartext .I >ciphertext .br .B auth/aescbc -d [ -in ] .I <ciphertext .I >cleartext .PP .B ipso [ .B -a -e -l -f -s ] [ .I file \&... ] .SH DESCRIPTION .I Secstore authenticates to a secure-store 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 -c prompts for a password change. .PP Option .B -g retrieves a file to the local directory; option .B -G writes it to standard output instead. Specifying .I getfile of .L \&. will send to standard output a list of remote files with dates, lengths and SHA1 hashes. .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 (see .IR authsrv (2)) instead of from .BR /dev/cons . .PP Option .B -p stores a file on the secstore. .PP Option .B -r removes a file from the secstore. .PP Option .B -s sets the dial string of the .IR secstore (8) server. The default is contained in the .BR $secstore environment variable. If the .B -s option is absent and .BR $secstore is empty, .IR secstore (1) will attempt to dial .BR tcp!$auth!secstore . .PP Option .B -u access the secure-store files belonging to .IR user . .PP Option .B -v produces more verbose output, in particular providing a few bits of feedback to help the user detect mistyping. .PP For example, to add a secret to the file read by .IR factotum (4) at startup, open a new window, type .LP .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 .LP 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, .I ipso will edit the .I secstore files and, if one of them is named .BR factotum , flush current keys from factotum and load the new ones from the file. If the .BR -e , .BR -f , or .BR -l options are given, .I ipso will just perform only the requested operations, 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 (under .LR -e ) and decrypts (under .LR -d ) using AES (Rijndael) in cipher block chaining (CBC) mode. Options .L i and .L n are as per .IR secstore , except that .L i reads from file descriptor 3. .SH SOURCE .B /rc/bin/ipso .br .B /sys/src/cmd/auth/secstore .SH SEE ALSO .IR factotum (4), .IR secstore (8) .SH DIAGNOSTICS Secstore sets error status on failure but will not print an error message when reading NVRAM or dialing the secstore server fails unless the .B -v flag is specified. .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.
