Publisher's Description:

Jasob JavaScript Obfuscator - Jasob JavaScript Obfuscator is a popular tool, enabling JavaScript and CSS driven Web pages to be compressed and obfuscated into supertight, bandwidth-optimized code, which is almost impossible for hackers to steal and reverse engineer.

When the code is not optimized, it takes the page longer to load. Besides, it makes the Web code easy to steal. Jasob JavaScript Obfuscator software is a perfect solution for those who want to make their Web pages faster and safer. Offering such compression technologies as comment removal, whitespace stripping, newline stripping and variable substitution, Jasob JavaScript Obfuscator can reduce the overall size of the code by 70%, making Web pages extremely quick to load and run in browsers. Obfuscated code also becomes impossible for hackers to understand and re-use.

The mechanism of obfuscation is very simple. Jasob JavaScript Obfuscator parses files with JavaScript code and replaces descriptive variable and function names, such as 'Customer', 'Salary', 'First Name' with meaningless names: 'd', 'g', 'm'. It also removes comments and unnecessary whitespace characters (space, tab, carriage return, line feed). The functionality of the code remains the same but source code changes dramatically. The same mechanism is used to compress and protect Cascading Style Sheet code (CSS).

Jasob's compression engine is equipped with language syntax, statement and keyword awareness and it optimizes code faultlessly even without breaking sloppy code with intermittent semicolon usage and other common errors.
