window.crypto.signText replacement plus enhancements
Download Install Compare

signTextJS plus is a Chrome extension that revitalizes the deprecated window.crypto.signText technology, widely used in government and banking digital signatures. It requires a native backend for full functionality, detailed on its homepage.

Beyond restoring automatic digital signature capabilities and certificate authority filtering removed from Firefox 35 onwards, signTextJS plus introduces valuable enhancements, including asynchronous operation, filtering by non-repudiation certificates, and support for the secure SHA-256 hash algorithm. This extension is essential for users needing reliable and modernized digital signature support within their browsers.

Extension safety

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.

signTextJS plus requires a few sensitive permissions. Exercise caution before installing.
