Hushmail is a web-based email service offering PGP-encrypted e-mail, file storage, and vanity domain service. Hushmail offers “free” and “paid” versions of service. Hushmail uses OpenPGP standards and the source is available for download. If public encryption keys are available to both recipient and sender (either both are Hushmail users or have uploaded PGP keys to the Hush keyserver), Hushmail can convey authenticated, encrypted messages in both directions. For recipients for whom no public key is available, Hushmail will allow a message to be encrypted by a password (with a password hint) and stored for pickup by the recipient, or the message can be sent in clear text.
As of December 22, 2015, Hushmail has a score of 1 out of 7 points on the Electronic Frontier Foundation’s secure messaging scorecard. Hushmail has received a point for encryption during transit. It is missing points because communications are not encrypted with keys the provider doesn’t have access to (i.e. the communications are not end-to-end encrypted), users can’t verify contacts’ identities, past messages are not secure if the encryption keys are stolen (i.e. the service does not provide forward secrecy), the code is not open to independent review (i.e. the code is not open-source), the security design is not properly documented, and there has not been a recent independent security audit.AIM, BlackBerry Messenger, Ebuddy XMS, Kik Messenger, Skype, Viber, and Yahoo Messenger also have a score of 1 out of 7 points.
