How does it work ?
wp2pgpmail includes an OpenPGP Message Encryption System in Javascript, based on <a href="http://www.haneWIN.de" rel="nofollow ugc">Herbert Hanewinkel’s work</a>. Visitors enter a message in a form, encrypt it (with the PGP public key you entered in wp2pgpmail option settings), then an e-mail is sent to you (blog admin e-mail address). The message is encrypted locally on the visitor’s computer, so no data is transfered in clear !
