Would this help?  Just add includes and an init function to register it.
I also have a Python function if anyone needs it.


static const char *ach[] = {
    "abcdefghijkamnbpqrstuvwxyzABCDEFGHcJKLMNdPQRSTUVWXYZ123456789eAB",
    "abcdefghjkamnbpqrstuvwxyzabcdefghcjkmndpqrstuvwxyzxyz23456789eab",
    "ABCDEFGHJKAMNBPQRSTUVWXYZABCDEFGHCJKMNDPQRSTUVWXYZXYZ23456789EAB",
};      

/*  
  usage:
    te_crypt <password>
    
    Encrypts a password
  
  Returns:
    The password in its encrypted form.
*/
    
int     
te_crypt(ClientData cData, Tcl_Interp *interp, int argc, char **argv)
{   
    char        salt[8];
    static int  initflag = 1;
    
    if (argc != 2)
    {
        Tcl_AppendResult(interp, "crypt: Invalid number of arguments", 0);
        return TCL_ERROR;
    }
    
    if (initflag)
        srandom(time(NULL)); 
    
    initflag  = 0;
    salt[0] = ach[0][random() % 64];
    salt[1] = ach[0][random() % 64];
    salt[2] = 0;

    Tcl_AppendResult(interp, crypt(argv[1], salt), 0);
    return TCL_OK;
}
