Posting-number: Volume 18, Issue 7
Archive-name: des-no-usa/Part01
Moderator's note:
This is a posting of DES routines suitable for use with MIT's kerberos.
It was created in Finland, and is being posted from Australia, and so
is entirely free of US export controls. I don't usually make
comp.sources.unix postings that originate outside Australia, but there
is no European sub-moderator (yet?) and this is rather a special case.
Where possible I will be taking special care to make sure that as much
of the net as is possible receives this posting without it having passed
through the US on the way. Unfortunately there is no way I can make
that true for everyone.
The following note is from the original author (Antti Louko) ...
Here is my DES-package. I hope that the lack of documentation
doesn't prevent posting this package in comp.sources.unix. I have
tried to implement library functions to match those of
kerberos-des-package. So kerberos manual pages give some hints what
the library functions do.
As I have said earlier, at least the library functions should be
compiled with gcc, if one wants the best performance. If it is needed
I (or somebody else with gcc) can provide assembler- or .o- files for
VAX- and SUN3- architecures. These files should be checksummed of
course to prevent any tampering. :-)
Antti Louko (alo@kampi.hut.fi)
Since that was written I have received an updated version that does include
a man page for the library routines.
I have added Makefiles for standard make (those in the original were
for GNU make only). Note, these are very primitive Makefiles, if you
change anything, "make clean" and recompile from scratch.
I also added some "#ifdef BSD" lines to give this a reasonable chance of
compiling in a sys V environment (at the expense of giving up the -t (timing)
option to des-certify, and of leaving echo enabled when requesting passwords).
I am sure that if someone was to provide Sys V versions of the code that ends
up missing and mail it to Antti, that a patch will be forthcoming.
I suggest that if you're located in the US you don't attempt to modify
these routines, their purity may be lost if tainted by contributions
from such a restrictive country.
Notes: you need "getopt(3)" for the programs to link, if your system
lacks it, you can get it from a comp.sources.unix archive near you.
If you remove the .h files from lib that "make clean" tells you you
can remove, you will need Larry Wall's "perl" program to replace them.
Also available in a comp.sources.unix archive near you.
You should define BIG_ENDIAN if you are on a big endian host. See
lib/des-private.h (I added the definitions for sparc and interdata,
no guarantees that the routines work on those hosts).
There are 2 files in the 'prog' directory that I uuencoded (now F1.uu
and F2.uu), I have no idea what they are useful for, if anything, however
should you need them, they will need to be uudecoded (to give F1 and F2).

X.SH NAME
Xdes \- encrypt and decrypt using DES algorithm
X.SH SYNOPSIS
X.B des

X.B -k
X.I keystring
X] [
X.B -e
X] [
X.B -d
X] [
X.B -x
X] [

X] [
X.B -c
X.I count
X] [
X.B -p
X] [
X.I inputfile
X[
X.I outputfile
X] ]
X.SH DESCRIPTION
X.I Des
Xreads
X.I inputfile
Xand writes the en/decrypted data to
X.I outputfile\c
X\&.
XIf file name is not given in command line, des uses standard input or output.
XThe
X.I keystring
Xis transformed by a one-way funtion into a 8-byte key,
Xwhich is then used by the algorithm. If no
X.I keystring
Xis given on command line,
Xdes asks one with getpass(3).
X.PP
XDes encrypts when given
X.B -e
Xflag and decrypts with
X.B -d\c
X\&.
XWith
X.B -x
Xflag des encrypts normally, but it doesn't produce any encrypted
Xoutput, instead it prints 8-byte cryptographic checksum of input data.
XThe checksum is printed to standard error file.
XThis checksum can be used to verify whether the input data has been modified.
XIt is computationally hard to change the input data in such a way that
Xthe checksum wouldn't change.
X.B -X
Xis similar to
X.B -x
Xbut it prints the input data to output file unchanged.
XUsing this feature you can for example produce a compressed tar archive
Xand its checksum
Xat the same time with command:
X.PP
X(tar cf - dir | des -X | compress > dir.tar.Z) >& dir.cksum
X.PP
XWith
X.B -c
Xdes makes encryption
X.I count
Xtimes for each 8kbyte block.
XThis possibly makes the encrypted data harder to break.
X.PP
XBy default, des encrypts the data using cipher block chaining (CBC) mode.
XWith
X.B -p
Xflag, des uses
XPCBC mode, which makes it possible to detect if the data have been tampered
Xafter encryption.
X.SH FILES
X/dev/tty is used to read a keystring by getpass(3)

X.SH BUGS
XThis program is at most as strong as DES algorithm itself.
XSo, we urge the user to use this program only after he has assured
Xhimself that DES is strong enough AND he has read the source code of this
Xprogram and its libraries AND he has compiled the program himself with a
Xtroyan-free compiler. I DON'T GUARANTEE THAT THIS PROGRAM IS A DECENT
XENCRYPTION PROGRAM.

X.SH DESCRIPTION
XThese library functions implement DES-algorithm with different
Xvariations. Type
X.I C_Block
Xis a data type containing eight bytes of
Xinformation. The least significant bit of the first byte of
X.I C_Block
Xis bit number 1 as specified in DES standard.
X.I C_Block
Xis defined as follows:
X.PP
X.nf
X.nj
X.B typedef unsigned char des_u_char;
X.B typedef struct {
X.B des_u_char data[8];
X.B } C_Block;
X.fi
X.PP
XA key schedule must be computed before encryption routines can be used.
XThis is done with function
X.I des_set_key,
Xwhich computes
X.B schedule
Xfrom
X.I key.
X.I Des_ecb_encrypt
Xencrypts one block of data at
X.I *input
Xto
X.I *output
Xusing
X.I schedule.
XIf mode is
X.I DES_ENCRYPT,
Xthe data is encrypted; if mode is
X.I DES_DECRYPT,
Xthe data is decrypted. If initial permutation or/and
Xfinal permutation is not wanted, mode can be ored (|) with
X.I DES_NOIPERM
Xor/and
X.I DES_NOFPERM.
X.PP
X.I Des_cbc_encrypt
Xencrypts length bytes of data at
X.I *input
Xto
X.I *output
Xin cipher block chaining mode. Initial vector is at
X.I *ivec.
X.I *ivec
Xis also updated to contain the final vector.
X.PP
X.I Des_pcbc_encrypt
Xuses a modified cipher block chaining. This mode can
Xbe used to detect if encrypted data have been tampered. In pcbc mode
Xchanging ciphertext data affects all the following decrypted cleartext
Xdata.
X.PP
X.I String_to_key
Xfunction converts ascii string
X.I asckey
Xinto a DES key
X.I *key
Xusing one way function which is based on DES algorithm.
