Extracting a public key from key pair in key chain http://stackoverflow.com/questions/11467215/extracting-a-public-key-from-key-pair-in-key-chain Fortunately Apple released a Crypto Exercise Sample where everything i need can be found class SecKeyWrapper functions generateKeyPair and getPublicKeyBits . But after trying to use these functions I always get the same output for my public key for different.. public key for different key pairs instead of different public key bits for different key pairs . Implementation of my generateKeyPair and getPublicKeyBits Function I first create a key pair by calling generateKeyPairWithKeySizeInBits which seems to work.. key pairs . Implementation of my generateKeyPair and getPublicKeyBits Function I first create a key pair by calling generateKeyPairWithKeySizeInBits which seems to work fine afterwards I extract the public key bits with getPublicKeyBits and NSLog them.....
