SECSTORE(1) SECSTORE(1) NAME aescbc, ipso, secstore - secstore commands SYNOPSIS auth/secstore [ -cinv ] [ -(g|G) getfile ] [ -p putfile ] [ -r rmfile ] [ -s server ] [ -u user ] auth/aescbc -e [ -in ] <cleartext >ciphertext auth/aescbc -d [ -in ] <ciphertext >cleartext ipso [ -a -e -l -f -s ] [ file ... ] DESCRIPTION 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. Option -c prompts for a password change. Option -g retrieves a file to the local directory; option -G writes it to standard output instead. Specifying getfile of `.' will send to standard output a list of remote files with dates, lengths and SHA1 hashes. Option -i says that the password should be read from stan- dard input instead of from /dev/cons. Option -n says that the password should be read from NVRAM (see authsrv(2)) instead of from /dev/cons. Option -p stores a file on the secstore. Option -r removes a file from the secstore. Option -s sets the dial string of the secstore(8) server. The default is contained in the $secstore environment vari- able. If the -s option is absent and $secstore is empty, secstore(1) will attempt to dial tcp!$auth!secstore. Option -u access the secure-store files belonging to user. Option -v produces more verbose output, in particular pro- viding a few bits of feedback to help the user detect mistyping. For example, to add a secret to the file read by factotum(4) at startup, open a new window, type SECSTORE(1) SECSTORE(1) % 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 and delete the window. The first line creates an ephemeral memory-resident workspace, invisible to others and automati- cally 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 facto- tum. The ipso command packages this sequence into a convenient script to simplify editing of files stored on a secure store. It copies the named files into a local ramfs(4) and invokes acme(1) on them. When the editor exits, ipso prompts the user to confirm copying modifed or newly created files back to secstore. If no file is mentioned, ipso grabs all the user's files from secstore for editing. By default, ipso will edit the secstore files and, if one of them is named factotum, flush current keys from factotum and load the new ones from the file. If the -e, -f, or -l options are given, ipso will just perform only the requested operations, i.e., edit, flush, and/or load. The -s option of ipso invokes sam(1) as the editor insted of acme; the -a option provides a similar service for files encrypted by aescbc (q.v.). With the -a option, the full rooted pathname of the file must be specified and all files must be encrypted with the same key. Also with -a, newly created files are ignored. Aescbc encrypts (under `-e') and decrypts (under `-d') using AES (Rijndael) in cipher block chaining (CBC) mode. Options `i' and `n' are as per secstore, except that `i' reads from file descriptor 3. SOURCE /rc/bin/ipso /sys/src/cmd/auth/secstore SEE ALSO factotum(4), secstore(8) DIAGNOSTICS Secstore sets error status on failure but will not print an error message when reading NVRAM or dialing the secstore SECSTORE(1) SECSTORE(1) server fails unless the -v flag is specified. BUGS There is deliberately no backup of files on the secstore, so -r (or a disk crash) is irrevocable. You are advised to store important secrets in a second location. When using ipso, secrets will appear as plain text in the editor window, so use the command in private.
