cname(8)

NAME

cname

SYNOPSIS

cname [ -3bms ] [ -v ]

DESCRIPTION

cname prompts for a passphrase and reads, from standard

input, a list of CFS encrypted file names (e.g.,

"51051f97e31613b7"). It produces, on standard output, a corre

sponding list of cleartext names. By default, names are decrypt

ed using standard 2-key hybrid mode single-DES. The -3 option

specifies 2-key hybrid mode triple DES. -m specifies 1-key hy

brid MacGuffin. -s specifies SAFER-SK128. The -v option includes

the ciphertext names in the output.

All names must be specified one per input line, as indi

vidual path components (full path names are not accepted). If a

name cannot be decrypted to printable characters, "???" is print

ed in its place. This is the only way to detect an incorrect

passphrase.

cname is intended to assist in making sense of CFS direc

tories when no CFS daemon is available. It is also useful in lo

cating files from backups.

BUGS

Does not work with new format (1.3 and later) directories.

The program is easily confused by slightly wrong input.

It would be better if it could transparently translate the output

from other programs such as ls(1), tar(1) and dump(8).
