Obfuscation and encryption. NET development tools

. NET development tools, such as ilspy, can be easily decompiled to view the source code. To protect your own software, the software is generally encrypted, not only internal key data is encrypted, after the software is developed, the software is encrypted to prevent others from easily decompiling and viewing important data. I tried the obfuscation of reactor and the encrypted DLL and exe, after it is easy to confuse and encrypt files, they will not be easily cracked and viewed by the source code.

For example, DLL and exe encryption and obfuscation configurations are as follows:

Use ilspy to view the saved DLL and exe files as follows:

You can also see the DLL file method, but you can't see the specific code in the method, and the EXE file cannot be decompiled directly.

The above can easily prevent others from easily decompiling and viewing the source code. More work is required for deeper encryption and obfuscation. I used the reactor cracked version circulating on the Internet.
