PGP Suite – Encrypt Messages & Files автор Max

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.

• 🔐 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.
• 🗝 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. You can also add a custom name or note to any imported public key that lacks identifying information, so you can always tell your contacts apart.
• 🔑 Choose your encryption algorithm — When generating a new key pair, pick the algorithm and strength that suits you: RSA 4096 (recommended for maximum compatibility with other PGP tools), RSA 3072, RSA 2048, or one of the modern ECC options (Curve25519, P-256, P-384, P-521).
• 🔒 Persistent Vault — Store passwords, usernames, and private notes securely inside the extension. Each vault entry is encrypted with your own PGP key and saved to the browser's local storage, so it survives browser restarts. You need your passphrase to unlock, edit, or delete an entry — nothing is ever saved in plain text.
• Master password protection — Optionally encrypt all stored private keys behind a master password. Keys are locked at browser startup and unlocked on demand.

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.


Tor Browser treats every website as a private window. Because of this, extensions are not allowed to run by default. After installing PGP Suite, you need to enable the "Allow in Private Windows" permission for the extension — otherwise it will appear installed but won't work. The extension does not have access to information on any website you visit regardless. Only permission to store data in local storage.

How to do it: Either just check the checkbox while installing the addon or if already installed: go to about:addons → find PGP Suite → open its detail page → under Permissions, tick Run in Private Windows. You only need to do this once.


Permissions this extension holds:

This extension requests the minimum set of permissions needed to function. By design, we deliberately avoid requesting permissions we do not strictly need — the more access an extension has, the more damage it could do if it were ever compromised or turned malicious. Below is an exact account of what each permission grants and what it does not.

• storage — Read and write data to the browser's own local storage. Used exclusively to save your PGP keys, vault entries, master password verification data, and settings. It cannot access the storage of any website or other extension.
• downloads — Trigger file downloads. Used only when you export an encrypted or decrypted file or when you export a backup of all local storage which you can then import into another installation of Firefox or Tor Browser. It cannot read, intercept, or list your existing downloads.
• tabs — Open new browser tabs and pass messages between the extension's background script and its interface. It cannot read page content, or any data from tabs you have open. It cannot see what sites you visit.
• https://feedback.yourdev.net/* — Make network requests to this one specific URL only, used exclusively by the optional contact form. The extension has no other network access whatsoever. Before this contact form was added, the extension had zero network permissions. Used to send emails to the developer (Support questions/Bug reports)

Permissions this extension does not hold — and therefore cannot do:

• Cannot read, intercept, or modify web traffic — no webRequest permission.
• Cannot read the content of pages you visit — no activeTab or broad host permissions.
• Cannot read your browsing history — no history permission.
• Cannot read your bookmarks — no bookmarks permission.
• Cannot read cookies from websites — no cookies permission.
• Cannot silently read your clipboard — no clipboardRead permission.
• Cannot access your location, microphone, or camera.
• Cannot send desktop notifications — no notifications permission.

As with everything else in this extension, the full permission list is visible in the manifest.json file in the public source code. You do not have to take our word for any of the above.
