This is done by inserting a decryption routine into the assembly and calling the decryption code at runtime to return the original Strings.
The string encryption function allows you to select literal values of string data type to be encrypted. You have choice to apply a cryptography method for the string encryption. However, for example, an attacker trying to break a licensing routine would first focus attention on Strings having to do with licensing to locate the appropriate spot of code. Only specified strings will be encrypted/obfuscated.
Since Strings can provide useful clues for anyone trying to reverse-engineer your code it makes sense to protect your string data from spying eyes. You may select all strings to be encrypted. It will not prevent an absolute hacker from deciphering the conversion and seeing your data. Also you may mark some specific strings to obfuscate. Skater can make this more difficult by encrypting the strings in your .NET assembly.
Today, with mass communication and e-commerce taking place online, code obfuscation is more important than ever. A code obfuscator tool encrypts code so that it looks completely different, while maintaining its original functions. What is Code Obfuscation? Code Obfuscation refers to the practice of developers and coders intentionally obscuring their code, so that even if it were to get stolen in a data breach, it couldn't be used by anyone else.
