How to find out the modulus and exponent of RSA Public Key on iPhone/Objective C

http://stackoverflow.com/questions/3840005/how-to-find-out-the-modulus-and-exponent-of-rsa-public-key-on-iphone-objective-c

a solution I've found without using any external packages . First go to Apple's CryptoExercise example. Download the SecKeyWrapper class from there. The interesting function in that class is getPublicKeyBits. Link to the example http developer.apple.com..
