Do you have to pay to codesign an app on OS X?

Question

Due to the inclusion of Gatekeeper, you have to codesign your OS X apps (so your users won’t get a warning). It seems, though, that the only way to get it signed will involve paying the $99/year for a developer program. Is there a way to codesign an app for free?

Answer 1

The only way to get an app signed is to obtain a certificate from Apple for $99/year.
