Softplan-WebSigner
Softplan-WebSigner is a digital signature and PKI (public key infrastructure) browser integration tool used primarily in Brazil for accessing legal and government systems that require digital certificate authentication. It functions as a native messaging host between web browsers (Chrome, Chromium, Edge) and the underlying PKI infrastructure, allowing users to sign documents and access restricted portals like ESAJ (Electronic Judicial System). The app handles certificate management, signature generation, and secure communication with web-based services.
AI Recommendation
1 suggestionWe could not confirm whether a native Apple Silicon build of Softplan-WebSigner exists — the search results contain only Linux installation instructions and do not clarify the macOS architecture status. Softplan is a Brazilian company and this is a regional security tool, so public information is limited. If you rely on this app, contact Softplan directly to ask whether a native Apple Silicon version is available or planned before macOS 28 ships in September 2028, since an Intel-only build will stop launching on that release. You can reach out to Softplan through their official website or support channels. As a temporary measure, the Intel build continues to run under Rosetta 2 today, but you should not depend on this remaining available indefinitely.
