There is no doubt in this fact that Codesign certificate protects software from being tampered and also gives confidence about the app/software that it is maintained by Certificate Authority.
You have some document to sign with Codesign certificate in MAC OSX but don’t know how to do it. Here is the guide for you. Now sign your file in MAC OSX in a minute.
Before we begin, please make an IMPORTANT NOTE:
THERE ARE SOME CHANGES MADE BY APPLE IN SETTINGS OF GATEKEEPER. THIS MEANS THE WAY OSX HANDLES THE CERTIFICATES HAS CHANGED FROM OTHER NON-APPLE VENDOR AND GUIDES THE SYSTEM TO PROHIBIT CERTIFICATES NOT ISSUED BY APPLE. AFTER DECADES OF ALL APPLE OPERATING SYSTEMS ARE ABLE TO RECOGNIZE OTHER BIG CERTIFICATE AUTHORITIES BUT UNFORTUNATELY THERE IS NO CHANGE IN THE DEFAULT SETTING WHICH CAN ALLOW CERTIFICATES FROM OTHER CERTIFICATE AUTHORITIES. DUE TO THIS REASON, WE NO LONGER CLAIM WHETHER OTHER CA’S CERTIFICATES WILL WORK BE SUPPORTED BY OSX NATIVELY OR NOT. NEVERTHELESS IT SHOULD SUPPORT JAVA ON OSX PLATFORM.
If you have already collected your certificate on Mac then you can find it in Keychain Access Manager. But if you have used another system to collect the certificate, the follow below instructions:
codesign -s "Company Name" " /Applications/Utilities/My App.app"
Press Enter and confirm, if prompted. Now when your code is signed, how will you check whether it is successful or not in Mac OS X. You can that with:
Signature verification becomes very important part when it is coming from third-party source since the chances of software getting tampered is distorted. With the help of below command you can verify your signature.
codesign -v "/Applications/Utilities/My App.app"
If you don’t any response that means the app/software is signed and unaltered.
