Using SecKeyRawSign on the iPhone

Question

I'm trying to sign some data using SecKeyRawSign but I keep getting a -4 errSecUnimplemented. That seems strange since the documentation states that it is available in iPhone OS2.0 and later.

Has anyone been able to use this function? If so, are there any tricks involved?

Answer 1

The -4 errSecUnimplemented error was being caused by a bad reference to the private key used to sign the data. Confusing error for that situation. A errSecParam would have been nicer.
