Signer.Digital Digital Signature, PKI Chrome Extension Analysis

Listing positioning

The product positions itself as a Java-free solution for digital signatures, encryption, and certificate management within the browser. It emphasizes support for hardware tokens (Smartcards/USB) and provides APIs for developers to integrate signing into web applications.

Inferred product pattern

B2B PKI bridge for browser-based digital signing and identity verification.

Review-backed pain points

Users report the extension hanging indefinitely on 'talking to the server' and frustration with documentation when trying to integrate the tool into React applications.

Observed feature gaps

Lack of comprehensive modern JavaScript framework (e.g., React) implementation guides and intermittent connectivity reliability.

Support

While some users praise the prompt support from the CISPL team, others express frustration over unresolved technical bugs in government projects.

Reliability

Multiple reports of the tool failing to complete signatures, frequently getting stuck in a 'talking to server' loop regardless of system restarts.

Privacy

One review explicitly warns that the extension tracks data across websites and behaves like a virus, although this is a minority signal.
