Also, all the routines +used for passphrase file maintenance have been moved to tphrase.c. + +The library has been optimized (a bit) for space instead of speed. Since +authentication is usually only done once, this isn't a big problem. Modern +CPUs are plenty fast for this task, and even 100 MHz CPUs are fine. If you +really need the speed, get the regular distributions. + +Note that if the server sends the client a prime that the client doesn't +know about, the client MUST test for primality. Since this is pretty +expensive, and takes 30 seconds on a 100 MHz machine, and uses lots of code, +I've removed that ability from the client. So only KNOWN primes can be +used. You can still generate new ones with tconf, but you have to install +them in the table of known primes (pre_params) in t_getconf.c that's common +to the client and server, and recompile. The configuration file is gone. + +The default prime (the last entry in the table) is 1024 bits; there are +others with more bits but they will be correspondingly slower. + +The default tpasswd file (which is an ascii file that may be editted with a +regular text editor) contains two users: moo (passphrase "glub glub") and +"new user" (passphrase "this is a test"). Passphrases may be added or +changed with tphrase; you can also change the user's prime. To delete a +user, edit the tpasswd file and remove that line. The tpasswd file's +default name is DEFAULT_PASSWD in t_pwd.h. Note that you can't change a +user's username by editting the file: the username is encoded in the +verifier. If you change a username you must set a new passphrase with +tphrase. + +Here is an example session, using the supplied srvtest and clitest.
