Make this completely dependant on the exportable libcrypt, to avoid
duplication of effort. Also a large cleanup of the code, inspired by Brandon Gillespie.

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:

||||||
|

||||||
60 MHz R4400 | FreeSec 1.0 | FreeSec 0.2

FreeBSD, except for the Makefile.
|

|
|

FreeSec was written by David Burren <davidb@werj.com.au>
|
|
||||||
|
|

A few bugs in the original FreeSec release have been fixed.

In order to make libcrypt binaries exportable from the USA,
|
|
||||||
only the symbol _crypt() (later to be changed to ___crypt())
|
|
||||||
is exported from libcrypt.
|
|
||||||
|
|
||||||
This source code was developed outside the USA, and can be
|
|

obtained outside the USA.

|
|
||||||
.Ft char
|
|
||||||
.Fn *crypt "const char *key" "const char *setting"
|
|
||||||
.Sh DESCRIPTION
|
|
||||||
The
|
|
||||||
.Fn crypt
|
|
||||||
function performs password encryption, based on the
|
|
||||||
.Tn NBS
|
|
||||||
Data Encryption Standard (DES).
|
|
||||||
Additional code has been added to deter key search attempts.
|
|
||||||
The first argument to
|
|
||||||
.Nm crypt
|
|
||||||
is a
|
|
||||||
.Dv null Ns -terminated
|
|
||||||
string, typically a user's typed password.
|
|
||||||
The second is in one of three forms:
|
|
||||||
if it begins with an underscore (``_'') then an extended format is used
|
|
||||||
in interpreting both the the key and the setting, as outlined below.
|
|
||||||
if it begins with the string ``$1$'' then an exportable format is used.
|
|
||||||
.Ss Extended crypt:
|
|
||||||
.Pp
|
|
||||||
The
|
|
||||||
.Ar key
|
|
||||||
is divided into groups of 8 characters (the last group is null-padded)
|
|
||||||
and the low-order 7 bits of each each character (56 bits per group) are
|
|
||||||
used to form the DES key as follows:
|
|
||||||
the first group of 56 bits becomes the initial DES key.
|
|
||||||
For each additional group, the XOR of the encryption of the current DES
|
|
||||||
key with itself and the group bits becomes the next DES key.
|
|
||||||
.Pp
|
|
||||||
The setting is a 9-character array consisting of an underscore followed
|
|
||||||
by 4 bytes of iteration count and 4 bytes of salt.
|
|
||||||
These are encoded as printable characters, 6 bits per character,
|
|
||||||
least significant character first.
|
|
||||||
The values 0 to 63 are encoded as ``./0-9A-Za-z''.
|
|
||||||
This allows 24 bits for both
|
|
||||||
.Fa count
|
|
||||||
and
|
|
||||||
.Fa salt .
|
|
||||||
.Ss "Traditional" crypt:
|
|
||||||
.Pp
|
|
||||||
The first 8 bytes of the key are null-padded, and the low-order 7 bits of
|
|
||||||
each character is used to form the 56-bit
|
|
||||||
.Tn DES
|
|
||||||
key.
|
|
||||||
.Pp
|
|
||||||
The setting is a 2-character array of the ASCII-encoded salt.
|
|
||||||
Thus only 12 bits of
|
|
||||||
.Fa salt
|
|
||||||
are used.
|
|
||||||
.Fa count
|
|
||||||
is set to 25.
|
|
||||||
.Ss "FreeBSD" or "Exportable" crypt:
|
|
||||||
.Pp
|
|
||||||
If the salt begins with ``$1$'' then the freely exportable
|
|
||||||
.Tn MD5
|
|
||||||
algorithm is used to calculate a hash value, from which the password string
|
|
||||||
is generated. The
|
|
||||||
.Tn MD5
|
|
||||||
derived routine is designed to be time-consuming like the DES based version.
|
|
||||||
.Ss Algorithm:
|
|
||||||
.Pp
|
|
||||||
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 DES key is used to encrypt a 64-bit constant using
|
|
||||||
.Ar count
|
|
||||||
iterations of
|
|
||||||
.Tn DES .
|
|
||||||
The value returned is a
|
|
||||||
.Dv null Ns -terminated
|
|
||||||
string, 20 or 13 bytes (plus null) in length, consisting of the
|
|
||||||
.Ar setting
|
|
||||||
followed by the encoded 64-bit encryption.
|
|
||||||
.Pp
|
|
||||||
The function
|
|
||||||
.Fn crypt
|
|
||||||
returns a pointer to the encrypted value on success, and NULL on failure.

This library (FreeSec 1.0) was developed outside the United States of America
|
|
||||||
as an unencumbered replacement for the U.S.-only NetBSD 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 is an original implementation of the DES and the crypt(3) interfaces
|
|
||||||
* by David Burren <davidb@werj.com.au>.
|
|
||||||
*
|
|
||||||
* An excellent reference on the underlying algorithm (and related
|
|
||||||
* algorithms) is:
|
|
||||||
*
|
|
||||||
* B. Schneier, Applied Cryptography: protocols, algorithms,
|
|
||||||
* and source code in C, John Wiley & Sons, 1994.
|
|
||||||
*
|
|
||||||
* Note that in that book's description of DES the lookups for the initial,
|
|
||||||
* pbox, and final permutations are inverted (this has been brought to the
|
|
||||||
* attention of the author). A list of errata for this book has been
|
|
||||||
* posted to the sci.crypt newsgroup by the author and is available for FTP.
|
|
||||||
*
|
|
||||||
* ARCHITECTURE ASSUMPTIONS:
|
|
||||||
* This code assumes that u_longs are 32 bits. It will probably not
|
|
||||||
* operate on 64-bit machines without modifications.
|
|
||||||
* It is assumed that the 8-byte arrays passed by reference can be
|
|
||||||
* addressed as arrays of u_longs (ie. the CPU is not picky about
|
|
||||||
* alignment).

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...
