title: iOS CommonCrypto reference
body: <p>I'm trying to find some sort of reference for the Apple's CommonCrypto library, because apparently Apple doesn't have any obvious link for that, and the ones given by Google are outdated, like this one below: </p>
  
  <p><a href="https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man3/Common%20Crypto.3cc.html" rel="nofollow noreferrer">https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man3/Common%20Crypto.3cc.html</a></p>
  
  <p>Any hints on this? Is there a better library I could use to develop an app with lots of cryptographic features?</p>
  
  <p>Thanks.</p>
