iOS簽名dyld: warning: could not load inserted library ‘dumpdecrypted.dylib‘ into hardened process

iOS利用dumpdecrypted.dylib注入解密時出現如下警告

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
           

經分析是 dumpdecrypted.dylib缺少簽名，重新給dumpdecrypted.dylib簽名後再用即可。

方法如下：

1、終端指令找出電腦中可簽名證書

security find-identity -v -p codesigning
           

2、cd到dumpdecrypted.dylib目錄，給dumpdecrypted.dylib簽名

codesign --force --verify --verbose --sign "iPhone Developer: Test TestName (1234TESTCODE)" dumpdecrypted.dylib
           

得到結果為

dumpdecrypted.dylib: signed Mach-O universal (armv7 armv7s arm64) [dumpdecrypted]
