title: OpenSSL and Apple Keychain integration
body: <p>We're using a multi platform application which should run on both Windows and Mac. Our application is based on OpenSSL as the SSL and related stuff supplier. It uses Client Certificate to establish secure connections and to identify the end user.</p>
  
  <p>We want to use Windows and Mac native certificate storages to ensure maximum security. Openssl has an engine to interact with Windows' Certificate Store (CAPI engine). However, we didn't manage to find such a solution for Mac's Keychain.</p>
  
  <p>Is there an integration between OpenSSL and Apple's Keychain?</p>
  
  <p>If not, what are your suggestion ?</p>
