title: Recommended *minimal* elliptic curve library in c
body: <p>Any recommendations for a c-library implementing elliptic curve cryptography - the smaller the better. </p>
  
  <p>I know openSSL provides it, but I want something as small as possible. It doesn't need any fancy stuff like constant time encryption / decryption / signing either.</p>
  
  <p>Bonus points for nice-looking code.</p>
