title: AES, Serpent or Twofish in C example?
body: <p>I found a lot of implementations of AES, Twofish and Serpent in C. But I don't really understand the examples. I only understand that some where provided with examples to invert a matrix.</p>
  
  <p>Can someone point me to an example or .c file for to encrypt/decrypt data represented by a  <code>char*</code>  and a password?</p>
