Features & Capabilities

Encryption Tool is a lightweight Chrome extension that encrypts and decrypts textual data and binary files using SHA-256. Add options to the right-click context menu to encrypt selected text to the clipboard, save encrypted data to synced storage, replace the original selection with encrypted content, or decrypt and copy/replace encrypted content. The extension works entirely offline to protect privacy.

Your passphrase is converted into a SHA-256-based private key while a random public key is used for operations; passphrases are never stored and cannot be recovered if forgotten. Common uses include securely sending passwords by email, archiving sensitive notes, and transferring secret data between devices. No data is sent to any server.

Is Encryption Tool Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Encryption Tool requires very minimum permissions.

Risk impact analysis details

Medium Enables sending notifications which can be spammed but have minimal direct security impact.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Encryption Tool is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
