yakuZza22 Posted September 3, 2009 Report Posted September 3, 2009 VMProtect 1.61VMProtect is a new generation software protection system, unlike other common market, the protection of software, VMProtect can modify the source code for software products, convert part of the code running in a virtual machine byte code (bytecode). You can imagine a virtual machine is different from the Intel 8086 processor system with the instructions of the virtual processors. For example, the virtual machine did not compare the two operands of the instruction nor the conditions to jump and unconditional jump instructions and so on. As a result, the cracker would need to develop a set of analytical engine to analyze and counter-compiled byte-code in order to decrypt the existing theory, break out the source code for those who want to restore is almost impossible.VMProtect 1.61 Quote
