ForeverCrypt VS Mailvelope

• Swap keys, not secrets
  You each share a public key (a padlock) once — safe to post anywhere.
• Works in any app
  Type a message, hit Send, and it becomes one short FC1.… code.
• Quantum-resistant
  ML-KEM-768 (NIST FIPS 203) exchanges a one-time secret; XChaCha20-Poly1305 seals the words.
• Your key, always random
  Each install generates its own keypair from the OS secure RNG, and a Randomize button makes a fresh one anytime.
• The app being public is fine
  Security doesn't depend on the program being secret — everyone has the same ForeverCrypt.
• Plain-language walkthrough
  A built-in 7-step guide explains public vs. private keys, why Discord can't reverse a code, and how to check it's really your friend.
• 100% offline
  No accounts, no servers, no telemetry.

• User-Friendly Interface
  Mailvelope offers an intuitive interface, making it easy for users to encrypt and decrypt their emails directly within their webmail client.
• Integration with Webmail
  Mailvelope seamlessly integrates with popular webmail services like Gmail, Yahoo Mail, and Outlook, enhancing email security without needing to change email providers.
• Open Source
  Being open-source, Mailvelope's code can be reviewed and audited by the community, ensuring transparency and enhancing trust in its security.
• Cross-Platform Compatibility
  As a browser extension, Mailvelope can be used on any operating system that supports the Chrome or Firefox web browsers, providing flexibility for users across different platforms.
• PGP Encryption
  Mailvelope uses PGP (Pretty Good Privacy) encryption, which is a well-respected method of securing email communications, ensuring messages remain private between sender and recipient.

Possible disadvantages

• Requires Technical Knowledge
  Users need a basic understanding of public-key cryptography and PGP to effectively use Mailvelope, which may be challenging for non-technical users.
• Limited to Webmail
  Mailvelope is specifically designed for webmail services, so it may not be suitable for those who use desktop email clients.
• Manual Key Management
  Users are responsible for generating, managing, and sharing their encryption keys, which can be cumbersome and prone to user error.
• No Support for Attachments
  Mailvelope does not natively support encrypting email attachments, which may require additional steps for users who need to send files securely.
• Potentially Vulnerable to Browser Exploits
  As a browser extension, Mailvelope may be vulnerable to browser-based security threats, such as malicious extensions or exploits that could compromise its functionality.
