Full summary	CipherMail is a Chrome extension that enables secure email communication by encrypting messages and attachments using S/MIME technology. It generates certificates automatically for each email contact through an internal PKI, ensuring industry-standard email protection without manual setup. Key features include full compatibility with existing S/MIME clients like Outlook and Thunderbird, encryption of both plain text and HTML emails, a modern user interface with drag-and-drop file upload, browser notifications, embedded images, and support for SMTP and IMAP protocols. It also offers convenient contact management, email autocompletion, and token-based security against CSRF attacks. Seamlessly integrated with the offilive.com platform, CipherMail simplifies business email encryption and management.	The SendSafely Encryption for Chrome and Gmail extension offers seamless end-to-end encryption for your private emails and large file sharing directly within Gmail. Built on the trusted OpenPGP standard, it ensures that only you and your intended recipients can access your messages and attachments — not even SendSafely itself.

Recipients do not need to install any software; they can securely receive encrypted items via any web browser. Ideal for users seeking a robust, user-friendly solution to protect sensitive communications while using Google Mail and Chrome.
