About

Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.

About

JavaScript Obfuscator transforms readable JavaScript source code into an obfuscated and unintelligible form, preventing reverse engineering, tampering, and intellectual property theft while preserving full functionality and compatibility with the latest ECMAScript versions. It includes powerful features such as minification and compression for reduced file size and faster load times, dead code insertion to confuse static analysis, and domain- or IP-based locking to disable code execution outside authorized environments. The tool provides GUI-driven desktop batch processing that allows users to protect JavaScript embedded in HTML, PHP, JSP, or similar files with just a few clicks, and supports keeping initial comments or inserting custom headers into output files. Advanced controls let you exclude certain names from obfuscation and ensure consistent symbol renaming across multiple files.

About

The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.
