Thanks!\r\n\r\n@phamtieugiao , I have the same task \"dump the signing cert from the binary\". \r\nI find that the author of book \"MacOS and iOS Internals, Volume III: Security & Insecurity\" provide a tool called [jtool](http://www.newosxbook.com/tools/jtool.html) . This tool provides --sig option. "}}
