Saving SecKeyRef device generated public/private key pair on disk

http://stackoverflow.com/questions/5988735/saving-seckeyref-device-generated-public-private-key-pair-on-disk

the answer myself you can get the bytes for a public key using SecItemCopyMatching . NSData getPublicKeyBits OSStatus sanityCheck noErr NSData publicKeyBits nil NSMutableDictionary queryPublicKey NSMutableDictionary alloc init Set the public key query.. id kSecAttrKeyType queryPublicKey setObject NSNumber numberWithBool YES forKey id kSecReturnData Get the key bits. sanityCheck SecItemCopyMatching CFDictionaryRef queryPublicKey CFTypeRef publicKeyBits if sanityCheck noErr publicKeyBits nil queryPublicKey.. Get the key bits. sanityCheck SecItemCopyMatching CFDictionaryRef queryPublicKey CFTypeRef publicKeyBits if sanityCheck noErr publicKeyBits nil queryPublicKey release return publicKeyBits The above is from Apple's CryptoExercise. Not sure..
