Does NSURLDownload end up using OpenSSL to certify? In which case, it would run afoul of the problem that OS X OpenSSL ships with no CA chain.

No. None of Apple's security software uses OpenSSL; that library's in the OS for compatibility and because a lot of other open-source packages use it.


Apple's security software is all based on CDSA. Foundation and CFNetwork use the SecureTransport API in the Security framework, so they're using the same certificate database you see in the Keychain Access app.
