User reviews

Users appreciate Signer.Digital for its easy integration, robust digital signature features, and strong technical support. It is praised for simplifying digital signing in web applications and ERP systems across multiple browsers. However, multiple users report issues with signing failures, certificates not showing, and vague error states like 'talking to server' indefinitely. Documentation is criticized for being hard to understand, hindering usage. Some hardware compatibility limitations exist, and there is at least one alarming claim about malicious behavior which may be isolated or erroneous. Overall, it is a powerful tool requiring better documentation and reliability improvements.

Pros

Easy integration with web applications, especially for developers.
Provides comprehensive digital signature functionality including signing, encryption, verification, and authentication.
Good and responsive technical support team, helpful during implementation and troubleshooting.
Simplifies implementation of digital signatures in ERP and web-based solutions.
Supports multiple browsers and operating systems with smooth user interface.

Cons

Documentation is unclear or insufficient, making implementation difficult for some users.
Frequent issues with signing documents failing or never completing, showing 'talking to server' indefinitely.
Problems with certificate recognition or import where certificates do not show or signing does not work despite successful import.
Reports of extension behaving suspiciously or maliciously (rare and possibly isolated).
Not compatible with some hardware tokens like YubiKey and certain platforms like ICEGATE.

My experience with the Signer.Digital browser extension and its web library integration has been exceptional. The extension is intuitive, and well-suited for seamless digital signature implementation. The support team is highly responsive, which adds tremendous value during implementation or troubleshooting phases. Signer.Digital's browser extension is a powerful tool for developers working on digital signature workflows. I highly recommend it for any organization or developer looking to enhance their applications with secure digital signing capabilities.

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.

Signer.Digital Digital Signature, PKI requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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 Chrome extension.
