BAHardCodeEncoder

Encode all hard code string in objective-c project. Of course, you can decode the changes too.

1. Install and use

• (1) put files in /oc-class into your project
• (2) pipenv install
• (3) start encode/decode action by command:

  python param1 --encode/--decode param2

  param1: path of this script

  param2: root path of project

• (4) import NSString+BAHCCategory.h and BAHCDefenitions.h globally

Also, you can use option --encrypt/--decrypt to encrypt/decrypt individual content

2. Set rules of exception

You can set rules of exception by change these vlaues in BAHardCodeEncoder.py

• Exception_File_Names: file name
• Exception_File_Prefix: file name prefix
• Exception_File_Suffix: file name suffix
• Exception_Folder_Names: folder name
• Exception_Folder_Prefix: folder name prefix
• Exception_Folder_Suffix: folder name suffix
• Exception_String_Format_Specifiers: string format specifiers like %@. If string contain one of these, then shall skip it

You must skip these files: NSString+BAHCCategory.h, NSString+BAHCCategory.m, BAHCDefenitions.h, GTMBase64.h, GTMBase64.m, GTMDefines.h

3. Keep encoded content different

You should change Key_salt in BAHardCodeEncoder.py every time, to keep encoded content on code file alaways different

4. Self define encode logic

The default encode logic is AES, you can just change key and iv of it, or rewrite encode logic

4.1 Change key and iv of AES

Change AES_key and AES_iv in BAHardCodeEncoder.py

Length of Key and iv for AES must be a multiple of 16

4.2 Rewrite encode logic

You can make it by rewrite function __encryptFunc in BAHardCodeEncoder.py
