IPhone/Objective-c RSA encryption

Question

Hello,

I have been google-ing and researching for an answer on how to do a simple RSA encryption using objective-c on an iphone. The main problem i have is that i have been supplied the Exponent and Modulus as an NSData object and i need to then convert them to a SecKeyRef object in order to perform the RSA encryption.

Does anyone have any idea how to do that or have any useful hints?

Many thanks!

Answer 1

See here, that should get you on the right track

Answer 2

I ended up using OpenSSL in my project. and import the keys and encrypt using that library instead of the iPhone ones.
