Use CopyCertSubject() to check if CA cert is valid.

SecCertificateCopyPublicKey() is not available on iPhone. Use
CopyCertSubject() instead to see if the certificate returned by
SecCertificateCreateWithData() is valid.

Hi Vilmos,

Many thanks for your recent patches and your discussion with Nick and others on the curl-library hackers mailing list. As you seem to becoming more of a active/regular contributor could I please ask that you post you modifications as git patch files (either as attachments or git emails) to the mailing list rather than as pull requests.

Additionally, could I also ask that your commit messages follow our template commit message.

For more information about both of these points please see:

http://curl.haxx.se/dev/contribute.html

This will assist us in testing and pushing your contributions as well as allowing a wider audience access to them, being able to comment on them and assist in the development of them, especially as not everyone receives the automated pull request emails from GitHub.

Many thanks in advance

Kind Regards

Steve

Hey Steve,

sorry about that - I did not know about the guidelines. I'll send a patch to the list.
