title: CommonCrypto alternative to PBKDF2
body: <p>Since Apple has deprecated the use of openSSL in iOS I need an alternative to PBKDF2 in one of iOS Security frameworks. I tried to search CommonCrypto with no luck.</p>
  
  <p>Is there a fair alternative to PBKDF2 which is recommanded by Apple?
  i.e.  key derivation function (password based) in iOS (implemented by Apple)?</p>
  
  <p>P.S. I'm aware of <a href="https://stackoverflow.com/questions/8569555/pbkdf2-using-commoncrypto-on-ios">PBKDF2 using CommonCrypto on iOS</a> , I don't want to use openSSL since it is not recommanded by Apple, see <a href="https://stackoverflow.com/questions/7406946/why-is-apple-depricating-openssl-in-macos-10-7-lion">Why is Apple Deprecating OpenSSL in MacOS 10.7 (Lion)?</a> </p>
