MailCloak Pro is a groundbreaking new GPG encryption plug-in from Global Web Security Systems (gWebs). MailCloak was designed from the ground up to be the first encryption killer app for IE, Firefox and all mail clients. MailCloak Pro uses the GNU Privacy Guard (Aka. GnuPG, aka. GPG) to automatically encrypt your emails, attachments and drafts on webmail and email clients. We designed MailCloak to be extremely easy-to-use ? Simply create a public key, turn on MailCloak, and send your friends encrypted email. MailCloak will automatically attach your public key to all outgoing email, and automatically import your friend's public keys when they send theirs to you ? so simply send an email to another MailCloak user to begin communicating securely with GPG encrypted email. It usually takes two to tango, so they say, but you can try MailCloak solo by sending email to Cryptobot@gwebs.com. When you send email to Cryptobot with MailCloak installed, Cryptobot will extract your public key, and reply with an encrypted message and it is own GPG public key. You will then be able to send Cryptobot an encrypted reply! You can also use MailCloak to communicate with other GnuPG, Gpg4win, FireGPG and PGP users. Global Web Security also has a desktop application and Firefox add-on that allows all Microsoft Windows POP3 email users and Firefox users to send GPG encrypted email. If your friends do not have MailCloak Pro, you can point them to gwebs.com get their free copy of MailCloak. Note that MailCloak stores all of your keys and passwords on your own computer, so you will never have to worry about us sharing this information.
