A test project on the basics of protecting software from debugging, disassembly and modification.

Unsafe project was modified with such additions:

1. Strings are encrypted during the compile time;
2. Pass-check function immutability is checked by counting function's CRC;
3. Added five different methods for debugging detection such as:

• Checking debugger with IsDebuggerPresent();
• Checking BeingDebugged value in PEB structure;
• Checking NtGlobalFlag for debugger;
• Checking heap flags and force flags;
• Checking NtQueryInformationProcess;

4. Added four different disassembly countermeasures:

• Added assembly instructions of conditional branches;
• Added garbage assembly instructions;
• Added some self-modified assembly code;
• Added macroses for changing unvaluable bytes to assembly instructions;

Developped for MSVC/Windows Visual Studio compiler.
