title: Generating secret key for AES 256 Encryption from Keychain
body: <p>I am working on a project where I need to encrypt/decrypt some data locally. I am using <a href="https://github.com/RNCryptor/RNCryptor" rel="nofollow noreferrer">RNCryptor</a> for the encryption and decryption process. To do that I need to use key, i don't want to define that key from app side like:</p>
  
  <pre><code>NSString *password = @"Secret password";
  </code></pre>
  
  <p>Is there any way to define the key using any property from keychain so that I can use the same key without defining it in code base.</p>
