CFS_PASSWD(1)

NAME
cfs_passwd - change passphrase on cfs directory

SYNOPSIS
cfs_passwd directory

DESCRIPTION
cfs_passwd changes the passphrase associated with a Cryptographic File System (CFS) directory. cfs_passwd 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

SEE ALSO
cfsd(8), cfs_attach(1), cfs_mkdir(1)

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