All I can say is avid this - function if possible since MIT's output is endian dependent. - -Version 2.12 14/10/92 - Added MSDOS specific macro in ecb_encrypt which gives a %70 - speed up when the code is compiled with turbo C. - -Version 2.11 12/10/92 - Speedup in set_key (recoding of PC-1) - I now do it in 47 simple operations, down from 60. - Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov) - for motivating me to look for a faster system :-) - The speedup is probably less that 1% but it is still 13 - instructions less :-). - -Version 2.10 06/10/92 - The code now works on the 64bit ETA10 and CRAY without modifications or - #defines. I believe the code should work on any machine that - defines long, int or short to be 8 bytes long. - Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu) - for helping me fix the code to run on 64bit machines (he had - access to an ETA10). - Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov> - for testing the routines on a CRAY. - read_password.c has been renamed to read_passwd.c - string_to_key.c has been renamed to string2key.c - -Version 2.00 14/09/92 - Made mods so that the library should work on 64bit CPU's. - Removed all my uchar and ulong defs. To many different - versions of unix define them in their header files in too many - different combinations :-) - IRIX - Sillicon Graphics mods (mostly in read_password.c). - Thanks to Andrew Daviel (advax@erich.triumf.ca) - -Version 1.99 26/08/92 - Fixed a bug or 2 in enc_read.c - Fixed a bug in enc_write.c - Fixed a pseudo bug in fcrypt.c (very obscure). - -Version 1.98 31/07/92 - Support for the ETA10. This is a strange machine that defines - longs and ints as 8 bytes and shorts as 4 bytes. - Since I do evil things with long * that assume that they are 4 - bytes. Look in the Makefile for the option to compile for - this machine. quad_cksum appears to have problems but I - will don't have the time to fix it right now, and this is not - a function that uses DES and so will not effect the main uses - of the library. - -Version 1.97 20/05/92 eay - Fixed the Imakefile and made some changes to des.h to fix some - problems when building this package with Kerberos v 4. - -Version 1.96 18/05/92 eay - Fixed a small bug in string_to_key() where problems could - occur if des_check_key was set to true and the string - generated a weak key. - -Patch2 posted to comp.sources.misc -Version 1.95 13/05/92 eay - Added an alternative version of the D_ENCRYPT macro in - ecb_encrypt and fcrypt. Depending on the compiler, one version or the - other will be faster. This was inspired by - Dana How <how@isl.stanford.edu>, and her pointers about doing the - *(ulong *)((uchar *)ptr+(value&0xfc)) - vs - ptr[value&0x3f] - to stop the C compiler doing a <<2 to convert the long array index. - -Version 1.94 05/05/92 eay - Fixed an incompatibility between my string_to_key and the MIT - version. When the key is longer than 8 chars, I was wrapping - with a different method. To use the old version, define - OLD_STR_TO_KEY in the makefile. Thanks to - viktor@newsu.shearson.com (Viktor Dukhovni). - -Version 1.93 28/04/92 eay - Fixed the VMS mods so that echo is now turned off in - read_password. Thanks again to brennan@coco.cchs.su.oz.AU. - MSDOS support added. The routines can be compiled with - Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined. - -Patch1 posted to comp.sources.misc -Version 1.92 13/04/92 eay - Changed D_ENCRYPT so that the rotation of R occurs outside of - the loop. This required rotating all the longs in sp.h (now - called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM> - speed.c has been changed so it will work without SIGALRM. If - times(3) is not present it will try to use ftime() instead. - -Version 1.91 08/04/92 eay - Added -E/-D options to des(1) so it can use string_to_key. - Added SVR4 mods suggested by witr@rwwa.COM - Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If - anyone knows how to turn of tty echo in VMS please tell me or - implement it yourself :-). - Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS - does not like IN/OUT being used. - -Libdes posted to comp.sources.misc -Version 1.9 24/03/92 eay - Now contains a fast small crypt replacement. - Added des(1) command. - Added des_rw_mode so people can use cbc encryption with - enc_read and enc_write. - -Version 1.8 15/10/91 eay - Bug in cbc_cksum. - Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this - one out. - -Version 1.7 24/09/91 eay - Fixed set_key :-) - set_key is 4 times faster and takes less space. - There are a few minor changes that could be made. - -Version 1.6 19/09/1991 eay - Finally go IP and FP finished. - Now I need to fix set_key. - This version is quite a bit faster that 1.51 - -Version 1.52 15/06/1991 eay - 20% speedup in ecb_encrypt by changing the E bit selection - to use 2 32bit words. This also required modification of the - sp table. There is still a way to speedup the IP and IP-1 - (hints from outer@sq.com) still working on this one :-(. - -Version 1.51 07/06/1991 eay - Faster des_encrypt by loop unrolling - Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu) - -Version 1.50 28/05/1991 eay - Optimised the code a bit more for the sparc. I have improved the - speed of the inner des_encrypt by speeding up the initial and - final permutations. - -Version 1.40 23/10/1990 eay - Fixed des_random_key, it did not produce a random key :-( - -Version 1.30 2/10/1990 eay - Have made des_quad_cksum the same as MIT's, the full package - should be compatible with MIT's - Have tested on a DECstation 3100 - Still need to fix des_set_key (make it faster). - Does des_cbc_encrypts at 70.5k/sec on a 3100. - -Version 1.20 18/09/1990 eay - Fixed byte order dependencies. - Fixed (I hope) all the word alignment problems. - Speedup in des_ecb_encrypt. - -Version 1.10 11/09/1990 eay - Added des_enc_read and des_enc_write. - Still need to fix des_quad_cksum. - Still need to document des_enc_read and des_enc_write. - -Version 1.00 27/08/1990 eay - diff --git a/secure/lib/libdes/cbc3_enc.c b/secure/lib/libdes/cbc3_enc.c deleted file mode 100644 index a7b53ad..0000000 --- a/secure/lib/libdes/cbc3_enc.c +++ /dev/null @@ -1,88 +0,0 @@ -/* crypto/des/cbc3_enc.c */ -/* Copyright (C) 1995-1996 Eric Young (eay@mincom.oz.au) - * All rights reserved. - * - * This file is part of an SSL implementation written - * by Eric Young (eay@mincom.oz.au). - * The implementation was written so as to conform with Netscapes SSL - * specification.

In my implementation this is always the case. -- Selection of a small value for j will require more cycles through - the encipherment algorithm per unit of plaintext and thus cause - greater processing overheads. -- Only multiples of j bits can be enciphered. -- An error will affect the current and the following ciphertext variables. - -Output Feedback Mode (OFB) (des_ofb_encrypt()) -- a number of bits (j) <= 64 are enciphered at a time. -- The OFB mode produces the same ciphertext whenever the same - plaintext enciphered using the same key and starting variable. More - over, in the OFB mode the same key stream is produced when the same - key and start variable are used. Consequently, for security reasons - a specific start variable should be used only once for a given key. -- The absence of chaining makes the OFB more vulnerable to specific attacks. -- The use of different start variables values prevents the same - plaintext enciphering to the same ciphertext, by producing different - key streams. -- Selection of a small value for j will require more cycles through - the encipherment algorithm per unit of plaintext and thus cause - greater processing overheads. -- Only multiples of j bits can be enciphered. -- OFB mode of operation does not extend ciphertext errors in the - resultant plaintext output. Every bit error in the ciphertext causes - only one bit to be in error in the deciphered plaintext. -- OFB mode is not self-synchronising. If the two operation of - encipherment and decipherment get out of synchronism, the system needs - to be re-initialised. -- Each re-initialisation should use a value of the start variable - different from the start variable values used before with the same - key.

To minimise this possibility, -.B des -takes care to destroy the key argument immediately upon entry. -If your shell keeps a history file be careful to make sure it is not -world readable. -.LP -Since this program attempts to maintain compatability with sunOS's -des(1) command, there are 2 different methods used to convert the user -supplied key to a des key. -Whenever and one or more of -.B \-E, \-D, \-C -or -.B \-3 -options are used, the key conversion procedure will not be compatible -with the sunOS des(1) version but will use all the user supplied -character to generate the des key. -.B des -command reads from standard input unless -.I input-file -is specified and writes to standard output unless -.I output-file -is given. -.SH OPTIONS -.TP -.B \-b -Select ECB -(eight bytes at a time) encryption mode. -.TP -.B \-3 -Encrypt using triple encryption. -By default triple cbc encryption is used but if the -.B \-b -option is used then triple ecb encryption is performed. -If the key is less than 8 characters long, the flag has no effect. -.TP -.B \-e -Encrypt data using an 8 byte key in a manner compatible with sunOS -des(1). -.TP -.B \-E -Encrypt data using a key of nearly unlimited length (1024 bytes). -This will product a more secure encryption. -.TP -.B \-d -Decrypt data that was encrypted with the \-e option. -.TP -.B \-D -Decrypt data that was encrypted with the \-E option. -.TP -.B \-c -Generate a 16 character hexadecimal cbc checksum and output this to -stderr. -If a filename was specified after the -.B \-c -option, the checksum is output to that file. -The checksum is generated using a key generated in a sunOS compatible -manner. -.TP -.B \-C -A cbc checksum is generated in the same manner as described for the -.B \-c -option but the DES key is generated in the same manner as used for the -.B \-E -and -.B \-D -options -.TP -.B \-f -Does nothing - allowed for compatibility with sunOS des(1) command. -.TP -.B \-s -Does nothing - allowed for compatibility with sunOS des(1) command. -.TP -.B "\-k \fIkey\fP" -Use the encryption -.I key -specified. -.TP -.B "\-h" -The -.I key -is assumed to be a 16 character hexadecimal number. -If the -.B "\-3" -option is used the key is assumed to be a 32 character hexadecimal -number. -.TP -.B \-u -This flag is used to read and write uuencoded files.

Knowing that the key was derived from ASCII -radically reduces the time necessary for a brute-force cryptographic attack. -My attempt to remove this problem is to add an alternative text-key to -DES-key function. This alternative function (accessed via -.B -E, -D, -S -and -.B -3 -) -uses DES to help generate the key. -.LP -Be carefully when using the -u option. Doing des -ud <filename> will -not decrypt filename (the -u option will gobble the d option). -.LP -The VMS operating system operates in a world where files are always a -multiple of 512 bytes. This causes problems when encrypted data is -send from unix to VMS since a 88 byte file will suddenly be padded -with 424 null bytes. To get around this problem, use the -u option -to uuencode the data before it is send to the VMS system. -.SH AUTHOR -.LP -Eric Young (eay@mincom.oz.au or eay@psych.psy.uq.oz.au) diff --git a/secure/lib/libdes/des.pl b/secure/lib/libdes/des.pl deleted file mode 100755 index d80e7cb..0000000 --- a/secure/lib/libdes/des.pl +++ /dev/null @@ -1,552 +0,0 @@ -#!/usr/bin/perl -# des.pl - eric young 22/11/1991 eay@mincom.oz.au or eay@psych.psy.uq.oz.au -# -# Copyright (C) 1993 Eric Young -# -# 11 April 1996 - patched to circumvent Perl 5 (through 5.002) problem -# with sign-extension on right shift operations. -# Ed Kubaitis - ejk@uiuc.edu -# -# eay - 92/08/31 - I think I have fixed all problems for 64bit -# versions of perl but I could be wrong since I have not tested it yet :-). -# -# This is an implementation of DES in perl. -# The two routines (des_set_key and des_ecb_encrypt) -# take 8 byte objects as arguments. -# -# des_set_key takes an 8 byte string as a key and returns a key schedule -# for use in calls to des_ecb_encrypt. -# des_ecb_encrypt takes three arguments, the first is a key schedule -# (make sure to pass it by reference with the *), the second is 1 -# to encrypt, 0 to decrypt.

it is used to speed the -encryption process. -.PP -.I des_read_password -writes the string specified by prompt to the standard output, -turns off echo and reads an input string from standard input -until terminated with a newline. -If verify is non-zero, it prompts and reads the input again and verifies -that both entered passwords are the same. -The entered string is converted into a des key by using the -.I des_string_to_key -routine. -The new key is placed in the -.I des_cblock -that was passed (by reference) to the routine. -If there were no errors, -.I des_read_password -returns 0, --1 is returned if there was a terminal error and 1 is returned for -any other error. -.PP -.I des_read_2password -operates in the same way as -.I des_read_password -except that it generates 2 keys by using the -.I des_string_to_2key -function. -.PP -.I des_read_pw_string -is called by -.I des_read_password -to read and verify a string from a terminal device. -The string is returned in -.I buf. -The size of -.I buf -is passed to the routine via the -.I length -parameter. -.PP -.I des_string_to_key -converts a string into a valid des key. -.PP -.I des_string_to_2key -converts a string into 2 valid des keys. -This routine is best suited for used to generate keys for use with -.I des_3ecb_encrypt. -.PP -.I des_random_key -returns a random key that is made of a combination of process id, -time and an increasing counter. -.PP -Before a des key can be used it is converted into a -.I des_key_schedule -via the -.I des_set_key -routine. -If the -.I des_check_key -flag is non-zero, -.I des_set_key -will check that the key passed is of odd parity and is not a week or -semi-weak key. -If the parity is wrong, -then -1 is returned. -If the key is a weak key, -then -2 is returned. -If an error is returned, -the key schedule is not generated. -.PP -.I des_key_sched -is another name for the -.I des_set_key -function. -.PP -The following routines mostly operate on an input and output stream of -.I des_cblock's. -.PP -.I des_ecb_encrypt -is the basic DES encryption routine that encrypts or decrypts a single 8-byte -.I des_cblock -in -.I electronic code book -mode. -It always transforms the input data, pointed to by -.I input, -into the output data, -pointed to by the -.I output -argument. -If the -.I encrypt -argument is non-zero (DES_ENCRYPT), -the -.I input -(cleartext) is encrypted in to the -.I output -(ciphertext) using the key_schedule specified by the -.I schedule -argument, -previously set via -.I des_set_key. -If -.I encrypt -is zero (DES_DECRYPT), -the -.I input -(now ciphertext) -is decrypted into the -.I output -(now cleartext). -Input and output may overlap. -No meaningful value is returned. -.PP -.I des_3ecb_encrypt -encrypts/decrypts the -.I input -block by using triple ecb DES encryption. -This involves encrypting the input with -.I ks1, -decryption with the key schedule -.I ks2, -and then encryption with the first again. -This routine greatly reduces the chances of brute force breaking of -DES and has the advantage of if -.I ks1 -and -.I ks2 -are the same, it is equivalent to just encryption using ecb mode and -.I ks1 -as the key. -.PP -.I des_cbc_encrypt -encrypts/decrypts using the -.I cipher-block-chaining -mode of DES. -If the -.I encrypt -argument is non-zero, -the routine cipher-block-chain encrypts the cleartext data pointed to by the -.I input -argument into the ciphertext pointed to by the -.I output -argument, -using the key schedule provided by the -.I schedule -argument, -and initialisation vector provided by the -.I ivec -argument. -If the -.I length -argument is not an integral multiple of eight bytes, -the last block is copied to a temporary area and zero filled. -The output is always -an integral multiple of eight bytes. -To make multiple cbc encrypt calls on a large amount of data appear to -be one -.I des_cbc_encrypt -call, the -.I ivec -of subsequent calls should be the last 8 bytes of the output. -.PP -.I des_3cbc_encrypt -encrypts/decrypts the -.I input -block by using triple cbc DES encryption. -This involves encrypting the input with key schedule -.I ks1, -decryption with the key schedule -.I ks2, -and then encryption with the first again. -2 initialisation vectors are required, -.I ivec1 -and -.I ivec2. -Unlike -.I des_cbc_encrypt, -these initialisation vectors are modified by the subroutine. -This routine greatly reduces the chances of brute force breaking of -DES and has the advantage of if -.I ks1 -and -.I ks2 -are the same, it is equivalent to just encryption using cbc mode and -.I ks1 -as the key. -.PP -.I des_pcbc_encrypt -encrypt/decrypts using a modified block chaining mode. -It provides better error propagation characteristics than cbc -encryption. -.PP -.I des_cfb_encrypt -encrypt/decrypts using cipher feedback mode. This method takes an -array of characters as input and outputs and array of characters. It -does not require any padding to 8 character groups. Note: the ivec -variable is changed and the new changed value needs to be passed to -the next call to this function. Since this function runs a complete -DES ecb encryption per numbits, this function is only suggested for -use when sending small numbers of characters. -.PP -.I des_ofb_encrypt -encrypt using output feedback mode. This method takes an -array of characters as input and outputs and array of characters. It -does not require any padding to 8 character groups. Note: the ivec -variable is changed and the new changed value needs to be passed to -the next call to this function. Since this function runs a complete -DES ecb encryption per numbits, this function is only suggested for -use when sending small numbers of characters. -.PP -.I des_cbc_cksum -produces an 8 byte checksum based on the input stream (via cbc encryption). -The last 4 bytes of the checksum is returned and the complete 8 bytes is -placed in -.I output. -.PP -.I des_quad_cksum -returns a 4 byte checksum from the input bytes. -The algorithm can be iterated over the input, -depending on -.I out_count, -1, 2, 3 or 4 times. -If -.I output -is non-NULL, -the 8 bytes generated by each pass are written into -.I output. -.PP -.I des_enc_write -is used to write -.I len -bytes -to file descriptor -.I fd -from buffer -.I buf. -The data is encrypted via -.I pcbc_encrypt -(default) using -.I sched -for the key and -.I iv -as a starting vector. -The actual data send down -.I fd -consists of 4 bytes (in network byte order) containing the length of the -following encrypted data. The encrypted data then follows, padded with random -data out to a multiple of 8 bytes. -.PP -.I des_enc_read -is used to read -.I len -bytes -from file descriptor -.I fd -into buffer -.I buf. -The data being read from -.I fd -is assumed to have come from -.I des_enc_write -and is decrypted using -.I sched -for the key schedule and -.I iv -for the initial vector. -The -.I des_enc_read/des_enc_write -pair can be used to read/write to files, pipes and sockets. -I have used them in implementing a version of rlogin in which all -data is encrypted. -.PP -.I des_rw_mode -is used to specify the encryption mode to use with -.I des_enc_read -and -.I des_end_write. -If set to -.I DES_PCBC_MODE -(the default), des_pcbc_encrypt is used. -If set to -.I DES_CBC_MODE -des_cbc_encrypt is used. -These two routines and the variable are not part of the normal MIT library. -.PP -.I des_set_odd_parity -sets the parity of the passed -.I key -to odd. This routine is not part of the standard MIT library. -.PP -.I des_is_weak_key -returns 1 is the passed key is a weak key (pick again :-), -0 if it is ok. -This routine is not part of the standard MIT library. -.PP -.I crypt -is a replacement for the normal system crypt. -It is much faster than the system crypt. -.PP -.SH FILES -/usr/include/des.h -.br -/usr/lib/libdes.a -.PP -The encryption routines have been tested on 16bit, 32bit and 64bit -machines of various endian and even works under VMS. -.PP -.SH BUGS -.PP -If you think this manual is sparse, -read the des_crypt(3) manual from the MIT kerberos (or bones outside -of the USA) distribution. -.PP -.I des_cfb_encrypt -and -.I des_ofb_encrypt -operates on input of 8 bits. What this means is that if you set -numbits to 12, and length to 2, the first 12 bits will come from the 1st -input byte and the low half of the second input byte. The second 12 -bits will have the low 8 bits taken from the 3rd input byte and the -top 4 bits taken from the 4th input byte. The same holds for output. -This function has been implemented this way because most people will -be using a multiple of 8 and because once you get into pulling bytes input -bytes apart things get ugly! -.PP -.I des_read_pw_string -is the most machine/OS dependent function and normally generates the -most problems when porting this code. -.PP -.I des_string_to_key -is probably different from the MIT version since there are lots -of fun ways to implement one-way encryption of a text string. -.PP -The routines are optimised for 32 bit machines and so are not efficient -on IBM PCs. -.PP -NOTE: extensive work has been done on this library since this document -was origionally written. Please try to read des.doc from the libdes -distribution since it is far more upto date and documents more of the -functions. Libdes is now also being shipped as part of SSLeay, a -general cryptographic library that amonst other things implements -netscapes SSL protocoll. The most recent version can be found in -SSLeay distributions. -.SH AUTHOR -Eric Young (eay@mincom.oz.au or eay@psych.psy.uq.oz.au) diff --git a/secure/lib/libdes/des_locl.h b/secure/lib/libdes/des_locl.h deleted file mode 100644 index 87a2b4a..0000000 --- a/secure/lib/libdes/des_locl.h +++ /dev/null @@ -1,299 +0,0 @@ -/* lib/des/des_locl.h */ -/* Copyright (C) 1995-1996 Eric Young (eay@mincom.oz.au) - * All rights reserved. - * - * This file is part of an SSL implementation written - * by Eric Young (eay@mincom.oz.au). - * The implementation was written so as to conform with Netscapes SSL - * specification.
