HTTPS on iPhone - What kind of encryption?

Question

I'm using an NSMutableURLRequest in an iPhone app, that uses a Content-Type:

application/x-www-form-urlencoded

The protocol is https.

From what I understand, this means the app uses encryption. But, what kind of encryption? According to Apple's export compliance page, they need to know whether I use > 64-bit symmetric or > 1024-bit asymmetric algorithms.

I honestly have no idea whether I do or not! Is there any simple answer to this question?

Answer 1

Assuming the NSMutableURLRequest uses the standard root certificates stored on the phone, you may not have to worry about it at all.

Also the form encoding is not part of the connection security, it's just about how fields are passed to the server in the request. It's independent of HTTPS.
