I'm now happy that this is no longer needed. Libcrypto has
all its functionality, and all its consumers have been converted.

FreeSec - NetBSD libcrypt replacement
|
||||
|
||||
David Burren <davidb@werj.com.au>
|
||||
Release 1.0, March 1994
|
||||
|
||||
Document ref: $FreeBSD$
|
||||
|
||||
|
||||
Description
|
||||
===========
|
||||
This library is a drop-in replacement for the libcrypt used in U.S. copies
|
||||
of NetBSD, duplicating that library's functionality. A suite of verification
|
||||
and benchmark tools is provided.
|
||||
|
||||
FreeSec 1.0 is an original implementation of the DES algorithm and the
|
||||
crypt(3) interfaces used in Unix-style operating systems. It was produced
|
||||
in Australia and as such is not covered by U.S. export restrictions (at
|
||||
least for copies that remain outside the U.S.).
|
||||
|
||||
|
||||
History
|
||||
=======
|
||||
An earlier version of the FreeSec library was built using the UFC-crypt
|
||||
package that is distributed as part of the GNU library. UFC-crypt did not
|
||||
support the des_cipher() or des_setkey() functions, nor the new-style
|
||||
crypt with long keys. These were implemented in FreeSec 0.2, but at least
|
||||
one bug remained, where encryption would only succeed if either the salt
|
||||
or the plaintext was zero. Because of its heritage FreeSec 0.2 was covered
|
||||
by the GNU Library Licence.
|
||||
|
||||
FreeSec 1.0 is an original implementation by myself, and has been tested
|
||||
against the verification suite I'd been using with FreeSec 0.2 (this is not
|
||||
encumbered by any licence). FreeSec 1.0 is covered by a Berkeley-style
|
||||
licence, which better fits into the *BSD hierarchy than the earlier GNU
|
||||
licence.
|
||||
|
||||
|
||||
Why should you use FreeSec?
|
||||
===========================
|
||||
FreeSec is intended as a replacement for the U.S.-only NetBSD libcrypt,
|
||||
to act as a baseline for encryption functionality.
|
||||
|
||||
Some other packages (such as Eric Young's libdes package) are faster and
|
||||
more complete than FreeSec, but typically have different licencing
|
||||
arrangements. While some applications will justify the use of these
|
||||
packages, the idea here is that everyone should have access to *at least*
|
||||
the functionality of FreeSec.
|
||||
|
||||
|
||||
Performance of FreeSec 1.0
|
||||
==========================
|
||||
I compare below the performance of three libcrypt implementations. As can be
|
||||
seen, it's between the U.S. library and UFC-crypt. While the performance of
|
||||
FreeSec 1.0 is good enough to keep me happy for now, I hope to improve it in
|
||||
future versions. I was interested to note that while UFC-crypt is faster on
|
||||
a 386, hardware characteristics can have markedly different effects on each
|
||||
implementation.

Notes: The results tabled here are the average over 10 runs.
|
||||
The entry/exit code for FreeSec 0.2's des_cipher() is particularly
|
||||
inefficient, thus the anomalous result for single encryptions.
|
||||
|
||||
|
||||
As an experiment using a machine with a larger register set and an
|
||||
obscenely fast CPU, I obtained the following results:

|

.Sh DESCRIPTION
|
||||
The functions,
|
||||
.Fn encrypt ,
|
||||
.Fn setkey ,
|
||||
.Fn des_setkey
|
||||
and
|
||||
.Fn des_cipher
|
||||
provide access to the
|
||||
.Tn DES
|
||||
algorithm.
|
||||
.Fn setkey
|
||||
is passed a 64-byte array of binary values (numeric 0 or 1).
|
||||
A 56-bit key is extracted from this array by dividing the
|
||||
array into groups of 8, and ignoring the last bit in each group.
|
||||
That bit is reserved for a byte parity check by DES, but is ignored
|
||||
by these functions.
|
||||
.Pp
|
||||
The
|
||||
.Fa block
|
||||
argument to
|
||||
.Fn encrypt
|
||||
is also a 64-byte array of binary values.
|
||||
If the value of
|
||||
.Fa flag
|
||||
is 0,
|
||||
.Fa block
|
||||
is encrypted otherwise it is decrypted.
|
||||
The result is returned in the original array
|
||||
.Fa block
|
||||
after using the key specified by
|
||||
.Fn setkey
|
||||
to process it.
|
||||
.Pp
|
||||
The argument to
|
||||
.Fn des_setkey
|
||||
is a character array of length 8.
|
||||
The least significant bit (the parity bit) in each character is ignored,
|
||||
and the remaining bits are concatenated to form a 56-bit key.
|
||||
The function
|
||||
.Fn des_cipher
|
||||
encrypts (or decrypts if
|
||||
.Fa count
|
||||
is negative) the 64-bits stored in the 8 characters at
|
||||
.Fa in
|
||||
using
|
||||
.Xr abs 3
|
||||
of
|
||||
.Fa count
|
||||
iterations of
|
||||
.Tn DES
|
||||
and stores the 64-bit result in the 8 characters at
|
||||
.Fa out
|
||||
(which may be the same as
|
||||
.Fa in ) .
|
||||
The
|
||||
.Fa salt
|
||||
introduces disorder in the
|
||||
.Tn DES
|
||||
algorithm in one of 16777216 or 4096 possible ways
|
||||
(ie. with 24 or 12 bits: if bit
|
||||
.Em i
|
||||
of the
|
||||
.Ar salt
|
||||
is set, then bits
|
||||
.Em i
|
||||
and
|
||||
.Em i+24
|
||||
are swapped in the
|
||||
.Tn DES
|
||||
E-box output).
|
||||
.Pp
|
||||
The functions
|
||||
.Fn setkey ,
|
||||
.Fn encrypt ,
|
||||
.Fn des_setkey ,
|
||||
and
|
||||
.Fn des_cipher
|
||||
return 0 on success and 1 on failure.
|
||||
.Pp
|
||||
The
|
||||
.Fn setkey
|
||||
and
|
||||
.Fn des_setkey
|
||||
functions manipulate the same key space.

.Sh HISTORY
|
||||
This library (FreeSec 1.0) was developed outside the United States of America
|
||||
as an unencumbered replacement for the U.S.-only
|
||||
.Nx
|
||||
libcrypt encryption
|
||||
library.
|
||||
Users should be aware that this code (and programs staticly linked with it)
|
||||
may not be exported from the U.S., although it apparently can be imported.

This directory contains test programs to certify DES operation and to
|
||||
time the crypt() call (of curiosity value).
|
||||
|
||||
Simply type `make test` to run the tests.
|
||||
|
||||
The normal `make all` and `make install` that get done during library building
|
||||
and installation will build these programs BUT NOT INSTALL THEM. After all,
|
||||
they're only for testing...
