CipherMail Email Encryption

CipherMail for Android is an application that allows for secure email communication through the use of S/MIME 3.1 encryption and digital signing. It is compatible with popular email clients such as Outlook and Thunderbird, and can be used with the Android Gmail application. This means that users can easily integrate CipherMail into their existing email setup without having to switch to a new client.

One of the main features of CipherMail is its ability to encrypt both the message and attachments, ensuring that sensitive information remains protected. It also supports HTML emails, making it easy to send and receive visually appealing messages. The application automatically extracts certificates and supports Certificate Revocation Lists (CRLs) for added security. Users can also create self-signed certificates for a private PKI (Public Key Infrastructure).

It is important to note that CipherMail does not provide email retrieval functionality. Instead, it works in conjunction with an existing Android mail application, such as Gmail or K9, to retrieve encrypted messages. Additionally, digitally signed messages can only be verified by opening them as an .eml file, which may not be possible with all mail clients.

In order to function properly, CipherMail requires the Contacts permission to be granted. This allows the application to lookup recipients when composing a message. However, if this permission is not granted, the application will still work but recipients cannot be looked up.

For more information on how to use CipherMail for Android, users can refer to the documentation provided on the CipherMail website. There is also a community forum available for support and assistance. CipherMail is developed by a company based in Amsterdam, the Netherlands, and offers products for email protection. Installation packages are available for various operating systems, and a free Virtual Appliance is also available for VMware and Hyper-V.
