Using encrypted WebMail, users can send and receive secure email messages with Atmail. Providing an easy-to-use webmail interface to secure email encryption, utilizing industry-standard OpenPGP format to encrypt messages using 512 - 4096 bit encryption. Atmail includes the ability to sign outgoing messages, allowing the recipient to verify the authenticity of an email.
Atmail is an RFC2440-compliant application, utilizing a non-proprietary method for encrypting email using strong public key cryptography. The OpenPGP protocol defines standard formats for encrypted messages, signatures, and for exchanging public keys.
Users can generate a PGP key via the WebMail interface of Atmail, with a choice of key sizes ranging from 512- to 4096-bit.
All encryption, decryption, and message signing is provided within the WebMail Interface.
To send an encrypted secure email message, all the user needs is the recipient's public key ( stored in the Atmail address-book ). When composing an email message the user can encrypt the content with the recipients public key, ensuring that the message can only be decrypted by the intended recipient, even if intercepted.
Atmail provides users the option of sending their public key on outgoing secure email messages. It also provides the ability to update a contact's address-book with the PGP public-key.
Message signing is available via the encryption menu when composing an email message. This allows the recipient to check the authenticity of an email message (verify that the message was sent using your account, and not forged).
There are many security concerns with SMTP - primarily that messages are sent and stored in plain text. The solution is to send messages in encrypted form, rendering ineffective any interception and accounting for the possibility of poor physical security at endpoints. Atmail utilizes 512- to 4096-bit (military grade) encryption for sending messages via the WebMail interface.
Atmail uses the open-source GnuPG utility to provide the PGP functionality. This utility is supported by most Linux distributions and Unix variants, as well as Windows Operating Systems.
During installation, Atmail checks the default installation directory for the GnuPG binary (gpg). This path can be changed via the WebAdmin Interface.
By using the encryption features of Atmail, you can secure email communication with clients, employees, and customers. To test drive the feature, please visit the online demo and signup for a test account. You can also download and install the Atmail demo on your own server.
