NAME
       cpasswd - change	passphrase on cfs directory

SYNOPSIS
       cpasswd directory

DESCRIPTION
       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	 (cur-
       rently 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),	cattach(1), cmkdir(1)

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