Blowfish Software Development Kit
Version 1.1
(c) 1996 Markus Hahn & Cedric Reinartz
1. Disclaimer
~~~~~~~~~~~~~
This software is "as it is" .
The makers and developers of this package make no representation, warranty,
assurance or inducement, express or implied, as to its adequacy, sufficiency
or freedom from defect of any kind. Neither the makers or developers will
have any liability to any user resulting from the use of it nor are they
responsible for any data loss or computer failure resulting from any inherent
incompatibilities with any other software or hardware.
2. Introduction
~~~~~~~~~~~~~~~
This is the Blowfish System Development Kit.
It provides the basic functions to en-/decrypt data in ECB and CBC mode.
You can directly use it in Turbo/Borland Pascal, TASM/MASM and even
in MS Visual C++. Interfaces for other languages like Fortran or Cobol
are easy to implement.
To learn how Blowfish works, read BFCBCGR.TXT. Unfortunately it's only
in German (too less time), but you should be able to understand the
functionality of the BF-SDK easily by studying the examples in assembly,
Pascal or C++.
If you want to know more about Blowfish, data encryption and security, please
read

To learn how to use the provided sources read PASCAL.TXT for the Turbo-
Pascal part, ASM.TXT for the assembly part and CPPTXT for the C++ part.
We're interested in any feedback! If you have any questions, suggestions or
improvements, please leave us an e-mail.

4. Technical Notes
~~~~~~~~~~~~~~~~~~
This software needs at least:
- IBM compatible AT-system with an 80386SX processor or better
- DOS 3.0 or above
achieved speed: 1.8 MB/sec on a Pentium90
2.7 MB/sec on a Pentium133
The actual version (1.1) is designed for 16bit systems, so you
should be able to use it in every - DOS real mode application
- DOS 286 protected mode application
- Windows 3.x application flawlessly.
5. Copyrights
~~~~~~~~~~~~~
Blowfish is a data encryption algorithm which was published in the Dr.Dobb's
Journal magazine, issue #213 on April 1994. It was developed by Bruce Schneier
and is unpatented and placed in the public domain.
In the September issue 1995 of DDJ Blowfish was (after a sponsored contest)
still unbreaked.
The advantages of this encryption algorithm is its design for 32bit CPUs like
the 80386 and above achieving an excellent performance with a maximum
gain of security.
The Blowfish implementation used in this software was done by:

6. Distribution and usage limits
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The BF-SDK can be distributed freely if:
- all files are distributed together
- all files are unmodified
- no fee (excluding material and shipping costs) is taken
If you use BF-SDK 1.1 for your own private purpose or if you developed
a program which is totally free and not bundled with a non-free product,
you can do so without paying any money (to us or someone else).
For any other use (especially profit use) you have to contact Markus Hahn
and Cedric Reinartz.
In any case you have to:
- write a program documentation which contains the whole Copyright
statement (part 5) from this text.
- send us (both) a note that you are using it!
7. The real world
~~~~~~~~~~~~~~~~~
The BF-SDK is used in the following products:
* ASPICRYP by Cedric Reinartz, a DOS based TSR which hooks to an
ASPI-Manager and encrypts the data going to a SCSI-device using the
Blowfish algorithm in CBC mode.
You can get it at:
ftp.franken.de
/pub/crypt/misc/ASPICRxx.ZIP
ftp.garbo.uwasa.fi
/pub/crypt/ASPICRxx.ZIP
* Blowfish Advanced 7 (BFA7) by Markus Hahn
a fast, secure and comfortable file encryption utility
for 386+ and DOS. It'll soon be available for Windows 95, too.
You can get it at:
ftp.uni-stuttgart.de
/pub/systems/pc/security/BFA7xx.ZIP
ftp.garbo.uwasa.fi
/pub/crypt/BFA7xx.ZIP
8. The Future
~~~~~~~~~~~~~
It would be nice to have some CFB routines, which allows Blowfish
to work as a stream cipher, encrypting and decrypting single bytes,
although the performance will be decreased to about 12% of the
original one.
If you want to contribute something, send it to Cedric Reinartz
or Markus Hahn.

}[/code] CRC C D3DES This package is a DES-compatible encipherement package which makes it easy
to send and receive secret mail through electronic mailers.
The most interesting products are:
cipher (decipher) - the actual encipherment/decipherment program.
cipher.1 - the nroff compatible manual page for cipher (please read)
atob, btoa - Binary to ASCII converters from compress 4.0 package
cmail - A script to interface above with your mailer
To install:
Edit the Makefile:
Define -DBSD or not as appropriate
Change MANDIR and BINDIR as appropriate
Type "make"
You may get some compiler warnings about & in front of arrays, invalid
pointer combinations and optimization problems. These are OK. The
important thing is too see if the testsuite passes. If it does, the
make will terminate normally.
Type "make install"
You may want to read about the "~|" option to the BSD mailer and compose
"encr" and "decr" scripts.

-----------
WINCRDLL.ZIP is a collection of Windows DLL's, with source code, that
implements the popular strong cryptosystems and a hashing algorithm. This
package is freeware, you can do whatever you like with it as long as you
agree that I (the author) assume absolutely no responsibility for any
consequences. You should also be aware of any local restrictions on the use
of crypto software that may be in effect in your country.
This package implements the following:
DES The well known U.S. standard
IDEA A very strong cipher used in PGP
MD5 A secure hashing algorithm by noted cryptographer, Ron Rivest.
MDC For want of a better name, a cipher based on the strong
cryptographic properties of MD5.

+---------------------------+----------------------------------------------+ Diamond加密算法c DES压缩包 内含N多子包 This package contains 2 DOS executables of the ENIGMA program.
The brunigma.exe on this disk wasn't compiled from the C Source
included. I made use of a special (and really not portable)
library included with my compiler.
This is due to the fact that ANSI.SYS wasn't installed on the
Laptop of Prof. Dr. Brunnstein. I decided to compile an
executable that he could use too. Since ANSI.SYS isn't
installed on all Systems, I included this special version in the
package.
There are two disadvantages however:
1. If I had asked somebody to compile it on a Borland
Compiler, it would be far shorter.
(This also applies to enigma4j.exe.)
2. I could't hide the Cursor. It seems to appear always
at the wrong places.
To avoid these disadvantages, just compile the source
as ANSI.SYS Version. On a Borland Compiler
bcc enigma4j.c
should do it.
