In this article Xiaobian for you to introduce in detail "android device registration encryption algorithm how to achieve", the content is detailed, the steps are clear, the details are handled properly, I hope this "android device registration encryption algorithm how to achieve" article can help you solve doubts, following the editor's ideas slowly in-depth, together to learn new knowledge.

Decompilation of APK (Xgorgon)

1. Jadx opens apk and searches for xgorgon to locate init_gorgon

2. Read the pseudo code in init_gorgon (), and you will find that the series of operations performed by the latest version before calling native are the same as the old version, so just follow the old version.

3. If you read the pseudo code again, you will find that byte [] R0 = com.ss.sys.ces.a.leviathan (R14, R10, R0). This is to call the local so library for the final encryption.

4. Send a view of the final effect (crawl the comment list of the video)

Decompiler APK (device registration plaintext encryption)

1. Jadx opens apk and searches for EncryptorUtil to locate ttEncrypt

2. After reading the code, you can see that two parameters are passed in to call native, one is bArr (byte after plaintext compression), and the other is the length of bArr. As for what the incoming bArr is, just hook it.

3. Send another final result (sign up for device_id)
