dumpdecrypted 解密过程问题总结

1、签名问题

报错信息

dyld: warning: could not load inserted library 'dumpdecrypted.dylib' into hardened process because no suitable image found.  Did find:

dumpdecrypted.dylib: code signature in (dumpdecrypted.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

Abort trap: 6

解决方案使用ldid工具的ldid -S dumpdecrypted.dylib命令给dumpdecrypted.dylib签名

2、Xcode SDK版本与越狱手机iOS SDK版本不一致

dyld: Symbol not found: ___chkstk_darwin

  Referenced from: dumpdecrypted.dylib (which was built for iOS 14.0)

  Expected in: /usr/lib/libSystem.B.dylib

 in dumpdecrypted.dylib

Abort trap: 6

修改dumpdecrypted 文件夹中make脚本，修改CFLAGS = -target arm64-apple-ios12.0 ，版本号为越狱机器的版本号

重新make

3、编译架构问题

clang:error: invalid iOS deployment version '-target arm64-apple-ios12.0', iOS 10 is the maximum deployment target for 32-bit targets [-Winvalid-ios-deployment-target]

修改make脚本中的GCC_UNIVERSAL=$(GCC_BASE) -arch arm64  去除多余架构
