About this extension
PGP Suite brings complete OpenPGP encryption directly into Firefox/Tor on any platform. Android works as well — no command line, no external software, no accounts required, Tor compatible.
Whether you want to send a private message, share an encrypted file, or simply verify that a message hasn't been tampered with, PGP Suite handles it all from a clean sidebar that opens in seconds.
What you can do:
Who is this for?
Anyone who wants to send private messages without relying on a third-party service
People who need to share sensitive files securely by email or cloud storage
Windows users tired of outdated tools like GPG4USB or Kleopatra
Developers and sysadmins managing PGP keys without leaving the browser
Privacy-conscious users who want a portable PGP tool on a USB stick or live OS
Tor Browser users who regularly work with PGP-encrypted messages
Privacy by design
No installation hassle
Unlike desktop PGP tools, PGP Suite requires zero setup. There is nothing to install outside of Firefox. Keys are stored in the browser's local storage and travel with your Firefox profile — or you can export a backup and take them anywhere.
Whether you want to send a private message, share an encrypted file, or simply verify that a message hasn't been tampered with, PGP Suite handles it all from a clean sidebar that opens in seconds.
What you can do:
- 🔐 Encrypt & decrypt messages — Paste any text, select a recipient's public key, and get an armored PGP message ready to send anywhere: email, forums, chat, anywhere.
- 📁 Encrypt & decrypt files — Select any file from your computer, encrypt it with a recipient's public key, and download the result. The recipient decrypts it with their private key and gets the original file back, name and all.
- ✍️ Sign & verify — Sign messages with your private key so recipients can prove the message is authentically yours. Verify incoming signed messages from others.<br>
- 🗝️ Key management — Generate RSA key pairs, import and export keys, and store multiple key pairs for different identities. Imported public keys are saved for quick reuse.
- Master password protection — Optionally encrypt all stored private keys behind a master password. Keys are locked at browser startup and unlocked on demand.
