With the new liberalized Bureau of Export Administration encryption
regulations now in effect, I am finally able to release my "cruft" file
encryption package for Linux and generic UNIX. This is a medium security
symmetrical block cipher system, based on the "one-time pad" algorithm,
useful mainly for non-critical encryption of files on a workstation
or network. Open Source / GPL, of course. The 'lsm' file follows.

Title: cruft - a replacement for the missing UNIX 'crypt' command
Version: 0.2
Entered-date: 2000-01-14
Description: Linux and other free UNIX systems often ship with the 'crypt'
command deleted because of Dept. of Commerce restrictions
on anything that even hints at strong encryption. The
'cruft' package is intended as a drop-in replacement for
'crypt', being equivalent in functionality and even easier
to use than the original. It is unnecessary to specify
whether the target file is to be encrypted or decrypted,
as this is autodetected. The length of the key chosen and
the frequency with which the (random) key file is changed
determines the encryption "strength" of 'crypt'. Despite
being theoretically unbreakable, this implementation of
the onetime pad cipher should be regarded as only medium
in its security level because a) it writes a nine byte
characteristic signature as a header to encrypted files,
and b) the keys generated use the 'gcc' random function,
which is not, in fact, all that random. This is more than
sufficient security for non-critical files on a network
or workstation, but don't trust the crown jewels to it.
This package is released in full compliance with the revised
BXA regulations on encryption software, as of 01/14/00.
