MailCloak is an innovative new GPG encryption addon that will be installed on your Firefox browser. MailCloak was designed from the ground up to be the first encryption killer app for IE, FF & mail clients. The Firefox version of MailCloak uses the GNU Privacy Guard (Aka. GnuPG, aka. GPG) to automatically encrypt your emails, attachments and drafts on Gmail, Yahoo! Mail and Microsoft Live Hotmail. 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.Requirements:
