CipherMail for Android

CipherMail for Android is a powerful tool designed to enhance the security of your email communications. It enables you to send and receive S/MIME signed and encrypted emails directly from your Android device.

Key Features:

• S/MIME 3.1 Support: Compliant with X.509 and RFC 3280 standards, allowing for robust email encryption and digital signing.
• Compatibility with Android Gmail: Seamlessly integrates with the Android Gmail application, making it easy to manage your secure communications.
• Cross-Platform Compatibility: Works seamlessly with existing S/MIME clients like Outlook and Thunderbird, ensuring compatibility across different platforms.
• Full Message Protection: Both the message body and attachments are encrypted to ensure maximum privacy.
• HTML Email Support: Supports rich text formatting for emails, enhancing readability and user experience.
• Automatic Certificate Extraction: Simplifies the process of managing certificates, making it easier to maintain secure communication channels.
• CRL Support: Supports Certificate Revocation Lists via LDAP and HTTP protocols for enhanced security.
• Certificate Trust Lists: Allows for blacklisting or whitelisting certificates to control who can send you secure messages.
• LDAP Integration: Enables searching for certificates on LDAP servers, providing a centralized certificate management solution.
• Self-Signed Certificates: Allows you to generate self-signed certificates for a private Public Key Infrastructure (PKI).

Important Notes:

• Email Retrieval: CipherMail does not handle email retrieval; you need to use an existing Android mail application such as Gmail, K9, or the default Android email client to fetch encrypted emails.
• Clear Signed Messages: Clear signed messages can only be verified by opening them as .eml files. This ensures that the entire message is available for validation.
• O365 Configuration: Ensure that SMTP is enabled if you are using Office 365.

Permissions:

• Contacts Permission: Required to look up recipients when composing new emails. If this permission is not granted, the app will still function but recipients cannot be auto-suggested.

Documentation & Support:

• Documentation: Detailed documentation is available at CipherMail for Android Documentation.
