What is OpenPGP, and how is it involved in the Hushmail solution?
OpenPGP is a protocol for encrypting email using public key cryptography. It is based on PGP as originally developed by Phil Zimmermann. The OpenPGP protocol defines standard formats for encrypted messages, signatures, private keys, and certificates for exchanging public keys. Over the past decade, PGP, and later OpenPGP, has become the standard for nearly all of the world’s encrypted email. By becoming an IETF standard RFC2440, OpenPGP may be implemented by any company without payment of any licensing fees. Hushmail version 2.x is OpenPGP compliant. This compliance with the OpenPGP standard makes Hushmail accessible to more email users than ever before, thus ensuring that it continues to be the #1 choice in secure email systems.
