Chrome extension that enables digital signatures, encryption/decryption, and certificate management using hardware security devices (smartcards, USB tokens, HSMs) or local certificate stores, bridging web applications with PKI hardware

Web applications cannot directly access hardware security devices for cryptographic operations. This extension provides a bridge between web browsers and local hardware (smartcards, USB tokens, PFX files, certificate stores, HSMs) to perform digital signatures, encryption, and certificate operations without requiring Java Runtime (JRE).

1. User installs extension and native host application on their system. 2. Web developer integrates the extension's JavaScript API (sdscript.js) into their web page. 3. When signing/encryption is needed, the web page calls the API (e.g., SignerDigital.signPdfHash()). 4. Extension shows permission dialog for the website (Allow/Deny). 5. If licensed and allowed, extension detects connected smartcards/USB tokens. 6. User selects certificate and enters smartcard PIN (on Linux/Mac). 7. Host application performs the cryptographic operation via PKCS#11 driver. 8. Result is returned to the web application.

Target users: Web developers integrating digital signing into web applications / Users who need to sign documents (PDF, eReturns, XML) from browser using hardware tokens / Organizations using PKI-based authentication / Users in regulated industries (e.g., Indian GST/IT returns, ICP-Brazil, ITIDA Egypt) / Certificate Authorities for certificate enrollment workflows

The licensing system is B2B (site-level) rather than consumer-facing, making it unusual - need to verify if host application itself has separate pricing
Cannot verify the actual license server response or determine exact pricing model for site licenses
The 'completely free' wording in store detail may refer to the extension being free for end users while site licenses are paid
