Safester

Safester works like any email application - just write a message, attach files & add recipients.
You don’t have to manage keys or encryption parameters - Safester does all that for you.
You get notifications in your regular inbox when you get a Safester message.
Use your contacts' usual email address - Safester will invite them to retrieve their encrypted message.
Recipients who don't have Safester are invited to get a FREE account while their message is waiting in a draft folder.
The FREE edition provides a full-featured send & receive version, with unlimited Inbox size. It's totally free for anyone to receive all your encrypted messages with attachments.
Your messages and files are encrypted before being sent and only decrypted after the reception.
There is no way to intercept your messages, no backdoor, no master key, no pinky to tell.
We use OpenPGP, the most widely acclaimed standard for encryption and the most robust algorithms out there (AES, RSA...).
We use long keys of 2048 bits, as recommended by security experts.
All your messages are stored encrypted on our servers.
If our servers were "hacked" into, all messages are stored encrypted and are impossible to decrypt.
