Gone Native

• Remove all openssl dependencies
  • Functionality becomes tied to whatever version of openssl libraries
    are compiled into PHP, leading to difficulty predicting which ciphers
    are supported
  • openssl functions are difficult to use with very different bahaviour (e.g.
    little consistency on exceptions vs silent failure, some functions returning
    values while others place return values in parameters)
• phpseclib for all crypto functions
  • phpselcib 3.0 not yet stable so depend on "stable" fork
• Key class behaviour altered (interface remains same)
  • Asymmetric: Only permit one private key, and only return one signing key.
    Exception at creation for early failure.
