Blog Article

On the globe of program improvement, protecting your mental house is vital. When developing .Web programs in C#, one popular menace is code reverse engineering. Resources like ILSpy or JetBrains dotPeek make it possible for any individual to decompile your compiled .NET assemblies again into human-readable code. This will expose your online business logic, algorithms, and sensitive information and facts. To forestall this, developers normally use obfuscators—instruments that make the decompiled code difficult to understand and reverse-engineer.

Luckily, you don’t require to interrupt the lender to safe your C# code. Numerous free obfuscators might help safeguard your .Web applications.
