Encoding is for maintaining data usability and can be reversed by employing the same algorithm that encoded the content, i.e.If you are obscuring computer code, for example, the limitation is that the result must still be consumable by the computer or else the application will cease to function.Įxamples: JavaScript Obfuscator, ProGuard Summary Other times it is simply a manual process that takes time to work through.Īnother key thing to realize about obfuscation is that there is a limitation to how obscure the code can become, depending on the content being obscured. It, like encoding, can often be reversed by using the same technique that obfuscated it. It’s important to note that obfuscation is not a strong control (like properly employed encryption) but rather an obstacle. One common use is the the obfuscation of source code so that it’s harder to replicate a given product if it is reverse engineered.
