Preface
iOS applications store some pictures, resources, configuration information, and even sensitive data such as user information, certificates, private keys, etc. How to protect this data? You can use the Keychain provided by iOS to protect sensitive data, you can also use encryption technology, or use Ipa Guard to weaken the meaning of file names and increase the difficulty of cracking. To protect iOS apps from being decompiled, cracked or tampered with.
The Ipa Guard code obfuscation tool supports modifying the names of various resource images, js, mp3, xib, sb, json, html, etc. in the code to make them meaningless and increase the security of iOS applications. At the same time, you can also modify the md5, udid and other values of resource files, add visually invisible watermarks, and optimize and protect them.
1. File name obfuscation for sensitive files
File names often become the entry point for hacker attacks. The meaning of the file is determined by the file name. Targeted attacks are a common attack method for hackers. ipaguard modifies the names of sensitive files (various resource images, js, mp3, xib, sb, json, html in the code) in the ipa file to make them meaningless and increase the security of iOS applications.
2. Change the MD5 value of the file
Modify the md5, udid and other values of the resource files in the ios app ipa file to reduce ios's determination of application relevance and reduce the probability that applications developed with the same framework will be judged as junk and plagiarized and rejected.
3. Add invisible watermark processing
Watermarking image resources in iOS programs can effectively mark images without affecting the display effect of the images.
3. Compress html, js, css and other resources
Compressing html, js, css and other resources can reduce the size of the app, reduce the readability of the resources, and increase the difficulty of reverse cracking.
5. Delete debugging information in executable files
After ipa development is completed, some source code debugging information often remains. ipaguard can delete and process this information, which greatly increases the difficulty of code reversal.
