RSA Encryption-Decryption in iphone

http://stackoverflow.com/questions/788569/rsa-encryption-decryption-in-iphone

I have used SecKeyGeneratePair method of Security Security.h framework. I am getting public private keys as SecKeyRef objects. Can I access the key or print its value to console Can I get NSString or NSData object from it When i print the.. for your quick response. In case of RSA Encryption first I have to generate a key pair which is in the form of SecKeyRef objects. Then we will pass that reference to SecKeyEncrypt SecKeyDecrypt methods. when i encrypt decrypt locally it is working.. if i try to send the key encrypted data to server decrypt at server java implementation side I am not able to pass the SecKeyRef object to server as a key value. In java we have to get the string in string or byte array format to pass to the encryption..
