They mostly involve random number generation for use + with kerberos. They involve evil machine specific system calls + etc so I would normally suggest pushing this stuff into the + application and/or using RAND_seed()/RAND_bytes() if you are + using this DES library as part of SSLeay. + Redone the read_pw() function so that it is cleaner and + supports termios, thanks to Sameer Parekh <sameer@c2.org> + for the initial patches for this. + Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been + done just to make things more consistent. + I have also now added triple DES versions of cfb and ofb. + +Version 3.20 + Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com, + my des_random_seed() function was only copying 4 bytes of the + passed seed into the init structure.

So I dropped the 'out' + parameter, people should not be using this function. + +Version 3.18 30/08/95 + Fixed a few bit with the distribution and the filenames. + 3.17 had been munged via a move to DOS and back again. + NO CODE CHANGES + +Version 3.17 14/07/95 + Fixed ede3 cbc which I had broken in 3.16. I have also + removed some unneeded variables in 7-8 of the routines. + +Version 3.16 26/06/95 + Added des_encrypt2() which does not use IP/FP, used by triple + des routines. Tweaked things a bit elsewhere. %13 speedup on + sparc and %6 on a R4400 for ede3 cbc mode. + +Version 3.15 06/06/95 + Added des_ncbc_encrypt(), it is des_cbc mode except that it is + 'normal' and copies the new iv value back over the top of the + passed parameter. + CHANGED des_ede3_cbc_encrypt() so that it too now overwrites + the iv. THIS WILL BREAK EXISTING CODE, but since this function + only new, I feel I can change it, not so with des_cbc_encrypt :-(. + I need to update the documentation. + +Version 3.14 31/05/95 + New release upon the world, as part of my SSL implementation. + New copyright and usage stuff. Basically free for all to use + as long as you say it came from me :-) + +Version 3.13 31/05/95 + A fix in speed.c, if HZ is not defined, I set it to 100.0 + which is reasonable for most unixes except SunOS 4.x. + I now have a #ifdef sun but timing for SunOS 4.x looked very + good :-(. At my last job where I used SunOS 4.x, it was + defined to be 60.0 (look at the old INSTALL documentation), at + the last release had it changed to 100.0 since I now work with + Solaris2 and SVR4 boxes. + Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this + one out. + +Version 3.12 08/05/95 + As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>, + my D_ENCRYPT macro in crypt() had an un-necessary variable. + It has been removed. + +Version 3.11 03/05/95 + Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys + and one iv. It is a standard and I needed it for my SSL code. + It makes more sense to use this for triple DES than + 3cbc_encrypt(). I have also added (or should I say tested :-) + cfb64_encrypt() which is cfb64 but it will encrypt a partial + number of bytes - 3 bytes in 3 bytes out. Again this is for + my SSL library, as a form of encryption to use with SSL + telnet. + +Version 3.10 22/03/95 + Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls + to cbc3_encrypt, the 2 iv values that were being returned to + be used in the next call were reversed :-(. + Many thanks to Bill Wade <wade@Stoner.COM> for pointing out + this error. + +Version 3.09 01/02/95 + Fixed des_random_key to far more random, it was rather feeble + with regards to picking the initial seed. The problem was + pointed out by Olaf Kirch <okir@monad.swb.de>. + +Version 3.08 14/12/94 + Added Makefile.PL so libdes can be built into perl5. + Changed des_locl.h so RAND is always defined. + +Version 3.07 05/12/94 + Added GNUmake and stuff so the library can be build with + glibc. + +Version 3.06 30/08/94 + Added rpc_enc.c which contains _des_crypt.

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.

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/lib/libdes/asm/des-som2.pl b/lib/libdes/asm/des-som2.pl new file mode 100644 index 00000000000..911d985e847 --- /dev/null +++ b/lib/libdes/asm/des-som2.pl @@ -0,0 +1,308 @@ +#!/usr/local/bin/perl +# +# The inner loop instruction sequence and the IP/FP modifications are from +# Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> +# + +$prog="des-som2.pl";

-0,0 +1,130 @@ +First up, let me say I don't like writing in assembler. It is not portable, +dependant on the particular CPU architecture release and is generally a pig +to debug and get right. Having said that, the x86 architecture is probably +the most important for speed due to number of boxes and since +it appears to be the worst architecture to to get +good C compilers for. So due to this, I have lowered myself to do +assembler for the inner DES routines in libdes :-). + +The file to implement in assembler is des_enc.c. Replace the following +4 functions +des_encrypt(DES_LONG data[2],des_key_schedule ks, int encrypt); +des_encrypt2(DES_LONG data[2],des_key_schedule ks, int encrypt); +des_encrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3); +des_decrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3); + +They encrypt/decrypt the 64 bits held in 'data' using +the 'ks' key schedules. The only difference between the 4 functions is that +des_encrypt2() does not perform IP() or FP() on the data (this is an +optimization for when doing triple DES and des_encrypt3() and des_decrypt3() +perform triple des. The triple DES routines are in here because it does +make a big difference to have them located near the des_encrypt2 function +at link time.. + +Now as we all know, there are lots of different operating systems running on +x86 boxes, and unfortunately they normally try to make sure their assembler +formating is not the same as the other peoples. +The 4 main formats I know of are +Microsoft Windows 95/Windows NT +Elf Includes Linux and FreeBSD(?). +a.out The older Linux. +Solaris Same as Elf but different comments :-(. + +Now I was not overly keen to write 4 different copies of the same code, +so I wrote a few perl routines to output the correct assembler, given +a target assembler type. This code is ugly and is just a hack. +The libraries are x86unix.pl and x86ms.pl. +des586.pl, des686.pl and des-som[23].pl are the programs to actually +generate the assembler. + +So to generate elf assembler +perl des-som3.pl elf >dx86-elf.s +For Windows 95/NT +perl des-som2.pl win32 >win32.asm + +[ update 4 Jan 1996 ] +I have added another way to do things. +perl des-som3.pl cpp >dx86-cpp.s +generates a file that will be included by dx86unix.cpp when it is compiled. +To build for elf, a.out, solaris, bsdi etc, +cc -E -DELF asm/dx86unix.cpp | as -o asm/dx86-elf.o +cc -E -DSOL asm/dx86unix.cpp | as -o asm/dx86-sol.o +cc -E -DOUT asm/dx86unix.cpp | as -o asm/dx86-out.o +cc -E -DBSDI asm/dx86unix.cpp | as -o asm/dx86bsdi.o +This was done to cut down the number of files in the distribution. + +Now the ugly part. I acquired my copy of Intels +"Optimization's For Intel's 32-Bit Processors" and found a few interesting +things. First, the aim of the exersize is to 'extract' one byte at a time +from a word and do an array lookup. This involves getting the byte from +the 4 locations in the word and moving it to a new word and doing the lookup. +The most obvious way to do this is +xor eax, eax # clear word +movb al, cl # get low byte +xor edi DWORD PTR 0x100+des_SP[eax] # xor in word +movb al, ch # get next byte +xor edi DWORD PTR 0x300+des_SP[eax] # xor in word +shr ecx 16 +which seems ok. For the pentium, this system appears to be the best. +One has to do instruction interleaving to keep both functional units +operating, but it is basically very efficient. + +Now the crunch. When a full register is used after a partial write, eg. +mov al, cl +xor edi, DWORD PTR 0x100+des_SP[eax] +386 - 1 cycle stall +486 - 1 cycle stall +586 - 0 cycle stall +686 - at least 7 cycle stall (page 22 of the above mentioned document). + +So the technique that produces the best results on a pentium, according to +the documentation, will produce hideous results on a pentium pro. + +To get around this, des686.pl will generate code that is not as fast on +a pentium, should be very good on a pentium pro. +mov eax, ecx # copy word +shr ecx, 8 # line up next byte +and eax, 0fch # mask byte +xor edi DWORD PTR 0x100+des_SP[eax] # xor in array lookup +mov eax, ecx # get word +shr ecx 8 # line up next byte +and eax, 0fch # mask byte +xor edi DWORD PTR 0x300+des_SP[eax] # xor in array lookup + +Due to the execution units in the pentium, this actually works quite well. +For a pentium pro it should be very good. This is the type of output +Visual C++ generates. + +There is a third option. instead of using +mov al, ch +which is bad on the pentium pro, one may be able to use +movzx eax, ch +which may not incur the partial write penalty. On the pentium, +this instruction takes 4 cycles so is not worth using but on the +pentium pro it appears it may be worth while. I need access to one to +experiment :-). + +eric (20 Oct 1996) + +22 Nov 1996 - I have asked people to run the 2 different version on pentium +pros and it appears that the intel documentation is wrong. The +mov al,bh is still faster on a pentium pro, so just use the des586.pl +install des686.pl + +3 Dec 1996 - I added des_encrypt3/des_decrypt3 because I have moved these +functions into des_enc.c because it does make a massive performance +difference on some boxes to have the functions code located close to +the des_encrypt2() function. + +9 Jan 1996 - des-som2.pl is now the correct perl script to use for +pentiums. It contains an inner loop from +Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> which does raw ecb DES calls at +273,000 per second. He had a previous version at 250,000 and the best +I was able to get was 203,000. The content has not changed, this is all +due to instruction sequencing (and actual instructions choice) which is able +to keep both functional units of the pentium going. +We may have lost the ugly register usage restrictions when x86 went 32 bit +but for the pentium it has been replaced by evil instruction ordering tricks. + +13 Jan 1996 - des-som3.pl, more optimizations from Svend Olaf. +raw

A des_key_schedule is an expanded form of the des key. +A des_key is 8 bytes of odd parity, the type used to hold the key is a +des_cblock. A des_cblock is an array of 8 bytes, often in this library +description I will refer to input bytes when the function specifies +des_cblock's as input or output, this just means that the variable should +be a multiple of 8 bytes. + +The define DES_ENCRYPT is passed to specify encryption, DES_DECRYPT to +specify decryption. The functions and global variable are as follows: + +int des_check_key; + DES keys are supposed to be odd parity.

If it is a weak key, don't use it, try a different + one. If you are using 'random' keys, the chances of hitting a weak + key are 1/2^52 so it is probably not worth checking for them. + +int des_set_key( +des_cblock *key, +des_key_schedule schedule); + Des_set_key converts an 8 byte DES key into a des_key_schedule. + A des_key_schedule is an expanded form of the key which is used to + perform actual encryption. It can be regenerated from the DES key + so it only needs to be kept when encryption or decryption is about + to occur. Don't save or pass around des_key_schedule's since they + are CPU architecture dependent, DES keys are not.

What this means is that each 'DES' operation + inside the cbc mode is really an C=E(ks3,D(ks2,E(ks1,M))). + Again, this is cbc mode so an ivec is requires. + This mode is used by SSL. + There is also a des_ede2_cbc_encrypt() that only uses 2 + des_key_schedule's, the first being reused for the final + encryption. C=E(ks1,D(ks2,E(ks1,M))). This form of triple DES + is used by the RSAref library. + +void des_pcbc_encrypt( +des_cblock *input, +des_cblock *output, +long length, +des_key_schedule ks, +des_cblock *ivec, +int enc); + This is Propagating Cipher Block Chaining mode of DES.

Buf is where the string will end up and length is the + size of buf. Prompt is a string presented to the 'user' and if + verify is set, the key is asked for twice and unless the 2 copies + match, an error is returned.

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. The reason for this is that an identical bit stream would be + produced each time from the same parameters. This would be + susceptible to a ' known plaintext' attack. + +Triple ECB Mode (des_ecb3_encrypt()) +- Encrypt with key1, decrypt with key2 and encrypt with key3 again. +- As for ECB encryption but increases the key length to 168 bits. + There are theoretic attacks that can be used that make the effective + key length 112 bits, but this attack also requires 2^56 blocks of + memory, not very likely, even for the NSA. +- If both keys are the same it is equivalent to encrypting once with + just one key. +- If the first and last key are the same, the key length is 112 bits. + There are attacks that could reduce the key space to 55 bit's but it + requires 2^56 blocks of memory. +- If all 3 keys are the same, this is effectively the same as normal + ecb mode. + +Triple CBC Mode (des_ede3_cbc_encrypt()) +- Encrypt with key1, decrypt with key2 and then encrypt with key3. +- As for CBC encryption but increases the key length to 168 bits with + the same restrictions as for triple ecb mode. diff --git a/lib/libdes/des_crypt.3 b/lib/libdes/des_crypt.3 new file mode 100644 index 00000000000..9feb447129e --- /dev/null +++ b/lib/libdes/des_crypt.3 @@ -0,0 +1,508 @@ +.TH DES_CRYPT 3 +.SH NAME +des_read_password, des_read_2password, +des_string_to_key, des_string_to_2key, des_read_pw_string, +des_random_key, des_set_key, +des_key_sched, des_ecb_encrypt, des_3ecb_encrypt, des_cbc_encrypt, +des_3cbc_encrypt, +des_pcbc_encrypt, des_cfb_encrypt, des_ofb_encrypt, +des_cbc_cksum, des_quad_cksum, +des_enc_read, des_enc_write, des_set_odd_parity, +des_is_weak_key, crypt \- (non USA) DES encryption +.SH SYNOPSIS +.nf +.nj +.ft B +#include <des.h> +.PP +.B int des_read_password(key,prompt,verify) +des_cblock *key;

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/lib/libdes/des_enc.c b/lib/libdes/des_enc.c new file mode 100644 index 00000000000..d08fe65013a --- /dev/null +++ b/lib/libdes/des_enc.c @@ -0,0 +1,301 @@ +/* crypto/des/des_enc.c */ +/* Copyright (C) 1995-1997 Eric Young (eay@mincom.oz.au) + * All rights reserved. + * + * This package is an SSL implementation written + * by Eric Young (eay@mincom.oz.au). + * The implementation was written so as to conform with Netscapes SSL. + * + * This library is free for commercial and non-commercial use as long as + * the following conditions are aheared to.
