The "Artistic License"
|
||||
|
||||
Preamble
|
||||
|
||||
The intent of this document is to state the conditions under which a
|
||||
Package may be copied, such that the Copyright Holder maintains some
|
||||
semblance of artistic control over the development of the package,
|
||||
while giving the users of the package the right to use and distribute
|
||||
the Package in a more-or-less customary fashion, plus the right to make
|
||||
reasonable modifications.
|
||||
|
||||
Definitions:
|
||||
|
||||
"Package" refers to the collection of files distributed by the
|
||||
Copyright Holder, and derivatives of that collection of files
|
||||
created through textual modification.
|
||||
|
||||
"Standard Version" refers to such a Package if it has not been
|
||||
modified, or has been modified in accordance with the wishes
|
||||
of the Copyright Holder as specified below.
|
||||
|
||||
"Copyright Holder" is whoever is named in the copyright or
|
||||
copyrights for the package.
|
||||
|
||||
"You" is you, if you're thinking about copying or distributing
|
||||
this Package.
|
||||
|
||||
"Reasonable copying fee" is whatever you can justify on the
|
||||
basis of media cost, duplication charges, time of people involved,
|
||||
and so on. (You will not be required to justify it to the
|
||||
Copyright Holder, but only to the computing community at large
|
||||
as a market that must bear the fee.)
|
||||
|
||||
"Freely Available" means that no fee is charged for the item
|
||||
itself, though there may be fees involved in handling the item.
|
||||
It also means that recipients of the item may redistribute it
|
||||
under the same conditions they received it.
|
||||
|
||||
1. You may make and give away verbatim copies of the source form of the
|
||||
Standard Version of this Package without restriction, provided that you
|
||||
duplicate all of the original copyright notices and associated disclaimers.
|
||||
|
||||
2. You may apply bug fixes, portability fixes and other modifications
|
||||
derived from the Public Domain or from the Copyright Holder. A Package
|
||||
modified in such a way shall still be considered the Standard Version.
|
||||
|
||||
3. You may otherwise modify your copy of this Package in any way, provided
|
||||
that you insert a prominent notice in each changed file stating how and
|
||||
when you changed that file, and provided that you do at least ONE of the
|
||||
following:
|
||||
|
||||
a) place your modifications in the Public Domain or otherwise make them
|
||||
Freely Available, such as by posting said modifications to Usenet or
|
||||
an equivalent medium, or placing the modifications on a major archive
|
||||
site such as uunet.uu.net, or by allowing the Copyright Holder to include
|
||||
your modifications in the Standard Version of the Package.
|
||||
|
||||
b) use the modified Package only within your corporation or organization.
|
||||
|
||||
c) rename any non-standard executables so the names do not conflict
|
||||
with standard executables, which must also be provided, and provide
|
||||
a separate manual page for each non-standard executable that clearly
|
||||
documents how it differs from the Standard Version.
|
||||
|
||||
d) make other distribution arrangements with the Copyright Holder.
|
||||
|
||||
4. You may distribute the programs of this Package in object code or
|
||||
executable form, provided that you do at least ONE of the following:
|
||||
|
||||
a) distribute a Standard Version of the executables and library files,
|
||||
together with instructions (in the manual page or equivalent) on where
|
||||
to get the Standard Version.
|
||||
|
||||
b) accompany the distribution with the machine-readable source of
|
||||
the Package with your modifications.
|
||||
|
||||
c) give non-standard executables non-standard names, and clearly
|
||||
document the differences in manual pages (or equivalent), together
|
||||
with instructions on where to get the Standard Version.
|
||||
|
||||
d) make other distribution arrangements with the Copyright Holder.
|
||||
|
||||
5. You may charge a reasonable copying fee for any distribution of this
|
||||
Package. You may charge any fee you choose for support of this
|
||||
Package. You may not charge a fee for this Package itself. However,
|
||||
you may distribute this Package in aggregate with other (possibly
|
||||
commercial) programs as part of a larger (possibly commercial) software
|
||||
distribution provided that you do not advertise this Package as a
|
||||
product of your own.
|
||||
|
||||
6. Any programs linked with this library do not automatically fall
|
||||
under the copyright of this Package, but belong to whomever generated
|
||||
them, and may be sold commercially, and may be aggregated with this
|
||||
Package.
|
||||
|
||||
7. The name of the Copyright Holder may not be used to endorse or promote
|
||||
products derived from this software without specific prior written permission.
|
||||
|
||||
8. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR

||||

|
||||

This kit builds a DES encryption library and a DES encryption program.
|
||||
It suports ecb, cbc, ofb, cfb, triple ecb, triple cbc and MIT's pcbc
|
||||
encryption modes and also has a fast implementation of crypt(3).
|
||||
It contains support routines to read keys from a terminal,
|
||||
generate a random key, generate a key from an arbitary length string,
|
||||
read/write encrypted data from/to a file descriptor.
|
||||
|
||||
The implementation was written so as to conform with the manual entry
|
||||
for the des_crypt(3) library routines from MIT's project Athena.
|
||||
|
||||
destest should be run after compilation to test the des routines.
|
||||
rpw should be run after compilation to test the read password routines.
|
||||
The des program is a replacement for the sun des command. I believe it
|
||||
conforms to the sun version.
|
||||
|
||||
The Imakefile is setup for use in the kerberos distribution.
|
||||
|
||||
These routines are best compiled with gcc or any other good
|
||||
optimising compiler.
|
||||
Just turn you optimiser up to the highest settings and run destest
|
||||
after the build to make sure everything works.
|
||||
|
||||
I believe these routines are close to the fastest and most portable DES
|
||||
routines that use small lookup tables (4.5k) that are publicly available.
|
||||
The fcrypt routine is faster than ufc's fcrypt (when compiling with
|
||||
gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
|
||||
(on a sun3/260 168 vs 336).
