cpasswd1

Change passphrase on cfs directory

Usage

cpasswd directory

Overview

cpasswd changes the passphrase associated with a Cryptographic File System (CFS) directory. cpasswd prompts for the old passphrase, and, if it is correct, a new passphrase, which must be entered twice. Passphrases must contain at least a minimum number of characters (currently 16).

Only new format (CFS 1.3 or later) directories can have their passphrases changed.

Files

directory/...

known-plaintext hash of the assigned keys.

directory/..c

identifies the cipher algorithm.

directory/..k

encrypted key file

Releases

Unchanged in 3 releases since Debian 3.0 (Woody).

  1. 3.0–4.0

Bugs

One passphrase per encrypted directory; there is no provision (yet) for individual users' passphrases.
