      From: sendpornnotspan@gmail.com              oh u want to crack a game?       hexeditor should do the trick              The most common software crack is the modification of an application's       binary to cause or prevent a specific key branch in the program's execution.        This is       accomplished by reverse engineering the compiled program code using a       debugger such as SoftICE or gdb until the software cracker reaches the       subroutine that contains the primary method of protecting the software (or       by disassembling an executable file with a program such as IDA). The       binary is then modified using the debugger or a hex editor in a manner       that replaces a prior branching opcode with its complement or a NOP opcode       so the key branch will either always execute a specific subroutine or skip       over it. Almost all common software cracks are a variation of this type.       Software developers are constantly developing techniques such as code       obfuscation, encryption, and self-modifying code to make this modification       increasingly difficult.              Another example is a crack that removes the trial period from shareware or        trials making the product function as the full unlocked version. These        cracks are usually programs that patch the program executable and        sometimes the .dll or .so linked to the application. Similar cracks are        available for software that requires a hardware dongle. A company can        also break the copy preventions of programs that they have legally        purchased but that are licensed to particular hardware, so that there is        no risk of downtime due to hardware failure (and, of course, no need to        restrict oneself to running the software on bought hardware only).              ps one of my fav windows programs is "reshack"              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
