What is the .CRK File Extension?

.CRK File Extension Description:

The CRK file extension has only one use and that is to identify a certain crack file. The CRK file extension, when accessed, has information that is mostly illegal, and has the sole purpose of breaking into computer systems or computer softwares. This file extension is used to copy commercial software in an illegal way, through breaking different registration and copy-protection techniques being utilized by the software.

With the CRK file extension, the user can use software devices that were already cracked or have been removed with protection, like copy prevention, serial number, trial version, hardware key, CD check, and software annoyances such as adware and nag screens. Through the CRK file extension, users can use specific software as if it was bought from its original manufacturer.

Normally, a software or application needs a valid serial number and other security measures in order for the user to use it as a real program. Sometimes, if the software or application installed has no valid serial number entered, it can be used as a trial version having a 30-day grace period. Other methods in controlling the use of illegally copied and distributed software bombard the user with nag screens and adwares. However, with the cracking technology, these can be prevented. Software applications can be used normally even if it was illegally copied or distributed through using the CRK file extension.

Cracking of software, with the aid of the CRK file extension can be done by changing the software's binary, in order to cause or prevent a certain key branch needed when the program has to be executed. This can also be accomplished by using a reverse engineering technique. The compiled program code will use a debugger like SoftICE, GDB, MacsBug, and OllyDbg in order for the software cracker to reach the subroutine, which includes the basic method of protecting the software.

Once the binary can be accessed, it is then modified through the debugger. The debugger will replace a branching opcode with an NOP opcode. This way, the key branch will only have to execute a certain subroutine, or it may just skip it over. This is possible as long as the CRK file extension is available within the software installer.
