KeyController ChromeOS is a free Chrome add-on developed by Signaturit Solutions S.L. It allows users to sign documents with URL filtering in ChromeOS.

This add-on utilizes the certificates hosted in IvSign for enhanced security. It offers the ability to set usage rules based on URLs, allowing users to either enable signature only on specific URLs or reject signature requests on certain URLs.

When a user wants to sign a document, this plugin captures the URL and sends it to the signature engine. The engine verifies if the document can be signed on that particular URL and performs an audit. This ensures that the signing process is secure and controlled.

To use KeyController ChromeOS, users need to have the KeyController Driver software installed, which is provided upon purchasing IvSign. This software integration ensures a seamless experience and enables the full functionality of the add-on.

With KeyController ChromeOS, users can sign documents securely and efficiently, with the added benefit of URL filtering for enhanced control over signature requests.
