How annoying. According to the documentation, you're supposed to now use SecCertificateCopyKey() instead, but that function doesn't exist before Mojave. I shall have to think about a good solution to this.

that function doesn't exist before Mojave

Hmm... No pleasant alternatives. One obvious answer is - detect at the compilation time if the OS is Mojave or newer. Probably your user base doesn't have anything older than Mojave anyway...
