插件简介

查看插件说明、主要功能和适用场景。

🟢 A simple end-to-end encryption to secure your emails and attachments on Google, including Google Workspace, Business, and Enterprise using OpenPGP.

🟢 FlowCrypt lets you use PGP encryption by generating a private and public key. It uses the recipient’s public key to encrypt the email, and only the recipient’s private key can decrypt the message and reveal its content.

🟢 Adds a Secure Compose button to Gmail, allowing you to send private PGP-encrypted emails when you choose to.

🟢 We update the extension regularly (see the "Updated" field to the right).

FlowCrypt allows you to:

✔ Set up the extension in just a few clicks.

AI 产品解读

PGP end-to-end email encryption for Gmail via a Chrome extension

Enables users to send and receive PGP-encrypted emails and attachments directly within Gmail, securing email communications against interception

User installs extension → authenticates with Google OAuth → extension generates or imports PGP keys → user composes email in Gmail → clicks Secure Compose button → extension encrypts message with recipient's public key → recipient decrypts with their private key. The extension injects content scripts into mail.google.com to add encryption UI directly in Gmail's interface.

目标用户: Gmail users who need end-to-end email encryption / Google Workspace/Enterprise users handling sensitive communications / Privacy-conscious individuals and organizations

The changelog.txt references historical subscription and checkout functionality from 2017-2018 that appears to have been removed from the current codebase - could not verify if FlowCrypt has external paid plans on their website that integrate with the extension

付费分析

未识别到付费功能

No evidence of paid feature gating within the extension. Searches for 'premium', 'subscription', 'payment', 'billing', 'checkout', 'upgrade', 'stripe' in the source code returned no meaningful results (only HTTP status code constants, library wordlists, and historical changelog entries). The extension is open-source on GitHub (FlowCrypt/flowcrypt-browser). FlowCrypt may offer enterprise plans on their website, but the extension itself does not gate features behind payment or call any billing/license APIs.

置信度: 90

来源: AI / 高
需要登录: 是
登录理由: The extension requires Google OAuth authentication to access Gmail for sending/receiving encrypted emails. The manifest requests the 'identity' permission, and the source code implements full Google OAuth flow (GoogleOAuth.newAuthPopup) with scopes for gmail.compose, gmail.modify, email, openid, and profile. The setup flow requires acctEmail and idToken, and the popup redirects to setup if no account is configured. The core workflow of encrypting/decrypting Gmail messages requires being authenticated with a Google account.
