JScript.Encode is a method created by Microsoft used to obfuscate both server and Client-side JavaScript or VB Script source code in order to protect the source code from copying.[1] JavaScript code is used for creating dynamic web content on many websites, with the source code easily viewable, so this was meant to protect the code.
The encoding is a simple polyalphabetic substitution using three alphabets.[2]
How to use
[edit | edit source]A command line script encoder can be used to encode scripts.[1][3] To encode a HTML web-page file called default.htm, use the following command:
screnc.exe default.htm defaultenc.htm
It would output to a file called defaultenc.htm.
Weaknesses
[edit | edit source]It has been reverse engineered[2] and many websites provide an on-the-fly decoder.[4]
