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 corresponding list of cleartext names. By default, names are decrypted using standard 2-key hybrid mode single-DES. The -3 option specifies 2-key hybrid mode triple DES. -m specifies 1-key hybrid 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 individual path components (full path names are not accepted). If a name cannot be decrypted to printable characters, "???" is printed in its place. This is the only way to detect an incorrect passphrase.

cname is intended to assist in making sense of CFS directories when no CFS daemon is available. It is also useful in locating 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).
