The main function

ZFJObsLib is a professional iOS source code obfuscation tool. The specific functions include method obfuscation, attribute obfuscation, class name obfuscation, keyword obfuscation, adding garbage code, automatically creating garbage classes, deleting comments, modifying resource file Hash values, encrypting strings, and renovating resources Name, artificial obfuscation, obfuscated file name, obfuscated file directory, obfuscated thesaurus, obfuscated log, mapping list, sensitive word filtering, image compression, crawler service, modified project name, refurbished project UUID, automatic backup obfuscated project, custom ignore Attributes, custom ignore functions, custom ignore class names, interface color magic changes, etc.!!

Code obfuscation

In terms of code obfuscation, it mainly obfuscates the differentiated original code from four aspects: attribute obfuscation, function obfuscation, class name obfuscation, and keyword obfuscation. Users can also choose the degree of obfuscation!

Resource Refurbishment

For the image resource files in the project, the software can not only modify its HASH value, and automatically update the resource file name, but also add a confusing prefix to the resource file!

garbage code

For projects with less source code and relatively simple logic, the software can add garbage code to existing classes and automatically reference them, and can also create garbage classes and automatically instantiate and call them!

encrypted string

Encrypt and protect the plaintext strings in the project to prevent key business codes from being obtained by tools such as IDA!

delete comment

The software can automatically delete all types of comment codes in the project with one click to prevent code logic from leaking!

obfuscation project framework

The software differentiates the project framework by modifying the project name, confusing the project directory, and renovating the UUID with one click!

Sensitive word filtering

For the card review or rejection caused by sensitive words that may be quoted in the source code, the software can search for sensitive words and replace them automatically!

Interface magic change

If you don’t want to modify the UI and put the source code on the shelf directly, you can change the UI view through the magic change of the interface color!
