Clearsigning outbound gmail emails verifies in the browser, but they have bad signatures when verified by others/pasted into terminal.

Muito Bom!!!

Mark McKinlay2016年2月10日

Its works but it only works on one machine. The extension loads if you log into chrome elsewhere but the keys don't follow. I guess its secure but pretty inconvenient and possibly unusable for some.

Works well, at least in Chrome 47.0.2526.106 m (64-bit) on Windows 8.1. One suggestion: allow a decrypted pop-up window to remain open while searching (Ctrl+F) in the main Chrome window.

AI product read

PGP-based end-to-end email encryption for webmail services

Enables users to encrypt and decrypt emails and attachments directly within webmail interfaces (Gmail, Outlook, Nextcloud, Yahoo, etc.) using OpenPGP, providing privacy and security for email communications without leaving the browser

1. User installs extension and generates or imports PGP key pair. 2. When composing an email in a supported webmail service, the extension provides an encryption overlay/editor. 3. User selects recipients' public keys and encrypts the message. 4. Recipients with the extension and corresponding private key can decrypt the message. For Gmail specifically, Google OAuth is used to integrate with the mail interface.

Target users: Individual users seeking email privacy / Businesses and organizations requiring email encryption and compliance / Users of Gmail, Outlook, Nextcloud, Yahoo, and other webmail services

Source package is corrupted (zip extraction error: 'End of data reached (data length = 0, asked index = 4)') — no source files could be read or analyzed
Cannot verify in-extension login flows, feature gating, or payment prompts from source code
Cannot inspect background.bundle.js or app/app.html for runtime behavior

Monetization

No paid features detected

The extension itself is described as free and open-source for private users. A 'Mailvelope Business' product exists for organizations with enhanced features and premium support, but this appears to be a separate enterprise offering (likely a separate license/subscription on mailvelope.com), not features gated within the free extension via in-extension payment flows. The manifest shows no billing, subscription, or license-check APIs. No payment platform signals were found in the heuristic scan.

Confidence: 80
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The manifest declares OAuth2 configuration with Google (client_id, scopes for gmail.readonly, gmail.send, userinfo.email) and the identity permission. For Gmail integration—which is a primary use case—users must authenticate with their Google account. However, the extension may also work with other webmail providers (Outlook, Nextcloud, Yahoo, etc.) without requiring Google login, so login is destination-service-specific, not universally required for all workflows.
