I found a bunch of source code for some old key generators. They were for popular programs during there time.

#include <stdio.h>

#include <conio.h>

#include <string.h>

#include <stdlib.h>

main()

{

    int i ;

    char username[25] ;

    unsigned long reg=0 ;

    clrscr() ;

    printf("Enter User Name : ") ;

    gets(username) ;

    for (i=0;i<strlen(username);i++) reg+=username[i] ;

    printf("This is your Registration Number : DS%lu-%lu%lu-%lu\n",reg%9+0x43,reg,reg%5,reg>>2) ;

    return (0) ;

}

#include <stdio.h>

#include <conio.h>

#include <string.h>


main()

{

  char username[60],org[20] ;

  int i ;

  long eax,esi=0,edx,ecx,ebx ;

  clrscr() ;

  printf("Enter User Name : ") ;

  gets(username) ;

  if ((strlen(username)<6) || (strlen(username)>60))

   {

      printf("UserName must more than 6 char and less than 60 char !!!") ;

      return 0 ;

   }

   username[2]=0x09 ; username[5]|=0x55 ;

   do

  {

     strcat(username,".") ;

   }while (strlen(username)<60) ;


do

  {

     eax=esi ;

     edx=eax % 4 ;

     ebx=16 ; ecx=edx ;

     edx=0 ; edx=eax % ebx ;


    printf("This is your Registration Key : %s\n",username) ;

    return (0) ;

}

#include <stdio.h>

#include <conio.h>

#include <string.h>

#include <stdlib.h>

main()

{

    int i ;

    char username[25] ;

    unsigned long reg=0x0141D69C ;

    clrscr() ;

    printf("Enter User Name : ") ;

    gets(username) ;

    for (i=0;i<strlen(username);i++) reg+=((username[i]*((i>>1)+4))*(i^3)) ;

    printf("This is your Registration Number : %lu\n",reg) ;

    return (0) ;

}

I have tons more and in different languages but I don't feel like posting them all. I'll post more later.

[RobSoftware]

Nice post! I'd like to see more if you get the time to post more. Where did you get these from?

[dirkfirst]

Awesome! Post more :)

[TkTech]

good, but does anyone else notice all the #include's are empty?

[Void]

Ahh, wierd..... hmm. I guess the board took out the includes because they are in the source. Here is another one.

#include <stdio.h>

#include <conio.h>

#include <string.h>


unsigned long rutin(char param[]) ;


main()

{

char username[25],org[20] ;

unsigned long reg=0xdc955bfd ;

clrscr() ;

printf("Enter User Name : ") ;

gets(username) ;

reg+=rutin(username) ;

printf("Enter Organization : ") ;

gets(username) ;

reg+=rutin(username) ;

printf("This is your Registration Key : %lu\n",reg) ;

return (0) ;

}


unsigned long rutin(char param[])

{

int i ;

unsigned long edx=0,ebp=0,ebx=0,edi=0 ;

const int magicnumber[]={0x23, 0x73, 0x65, 0x72, 0x42, 0x26, 0x6E, 0x7A, 0x7C, 0x6D, 0x66, 0x4D, 0x31, 0x2F, 0x35, 0x28,

Odd, it still took them out

[Void]

They are still in the post if I edit them they just do not show up....

[Void]

Here is another one

[code]
#include<stdio.h>
#include<conio.h>
#include<string.h>
main()
{
int i ;
char username[25] ;
unsigned long reg=0,reg2=0,esi=0 ;
clrscr() ;
printf("Enter User Name : ") ;
gets(username) ;
strcat(username,"csca4") ;
for (i=0;i<strlen(username);i++)
{
reg2<<=4 ;
reg=username[i]+reg2 ;
reg2=reg ; reg&=0x0f000000 ;
if (reg!=0)
reg2^=(reg>>0x18) ;
reg2&=(~reg) ;
}
printf("This is your Serial Number : %lu\n",reg2) ;
return (0) ;
}

There's certainly lots of different codes for just one program, they all must work in different ways.

Its not all from the same program and each works independent of the others. These are VERY old key generators from previous versions of software. They don't work anymore for the software they were wrote for but they serve as a good example of how to write your own.

[DevilsCharm]

Oh they were all wrote for a specific program, I see. It is interesting looking over how a keygen for one thing has to be so different from one written for another.
