new pw generator, ideal for scripting
as the title says,
i've rewritten my previous program to make it more compatible with other OS's and to make it usefull for scripting.
i've tested it on slackware 10, RH9 and windows.
pwgenCL
here's the source (i don't post the executables anymore, if you want one, PM me):
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void very_easy2_password(int);
void easy_password(int);

void hard_password(int);
void hard2_password(int);
void very_hard_password(int);
void extreme_password(int);
int main(int argc, char** argv)
{
int characterset=0;
int password_length=0;
if((argc<3)|(argc>3))
