I wanted to make my own build of Textual the other day and needed a code signing certificate to complete the build. I decided to make single, long-lived certificate to that I could reuse for building multiple applications.
Open the "Keychain Access" application
bash open -a "Keychain Access"
Application menu > Certificate Assistant > Create a Certificate...
Configure your new certificate
- Name: Self-signed Applications
- Identity Type: Self Signed Root
- Certificate Type: Code Signing
- [x] Let me override defaults
- Change expiration date
- Validity Period (days): 3650
Just keep hitting Continue to accept defaults from here on out
Note: Xcode seems to cache certificate info on startup. If you had XCode open while you created this certificate, restart it.
I have since used this same certificate to build Growl and a couple of other apps. I'm thinking that I'll export the public certificate and import it on my other OSX hosts so I can share the compiled binaries from machine to machine without needing to recompile them.
