These are the start of a lot of work to clean up the FreeBSD eBones code. these changes include, but are not limited to: - Create prototypes for all the library routines - Make all the libraries compile clean with -Wall set - Fix numerous small bugs shown up in the above process - Prepare the code for libdes's removal to secure/ - add register, registerd and make_keypair to the make Lots more will follow in days to come.

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).
