## Description

CipherMail Email Encryption is an Android application designed to work alongside your existing mail app, enabling you to send and receive digitally signed and encrypted emails using S/MIME standards. It supports full S/MIME 3.1 features including X.509 certificates, email encryption, digital signing, and encrypted attachments. Compatible with popular mail clients such as Gmail, Outlook, and Thunderbird, CipherMail ensures your emails and attachments remain secure across platforms.

## Review summary

CipherMail Email Encryption is praised for effectively decrypting and opening encrypted .p7m email attachments on Android, supporting popular clients like Thunderbird and Outlook. Users appreciate its core functionality of reading encrypted emails without changing email clients. However, common issues include lack of integration with email apps leading to manual handling of attachments, poor UI design, missing default file associations, insufficient documentation on certificate management, and limited feature completeness especially in receiving encrypted emails. Overall, it solves a critical need but could benefit from improved usability and enhanced integration.
