CF is a Linux/Unix command line utility for editing/managing AES-encrypted text files. Multiple users can edit the same files using their own separate
passwords. It supports basic file locking, piping, adding, changing, removing, and listing keys. Editing sessions are as simple as typing "cf secretfile.cf"; CF asks for a password, decrypts the file, and starts an editor of choice. When the sessions ends, CF picks up the clear text and re-encrypts it. It takes care to let the clear files exist for as short periods of time as possible, and wipes them from memory and disk. It can be used for password management for single users or groups. It can also encrypt/decrypt streams when used in a pipe.
