SecuKit NX 1.0

SecuKit NX is a client-side security middleware developed by Korea Information Certificate Authority, Inc. (KICA). It enables digital signatures, encryption, and certificate management for websites and desktop applications that rely on Korea’s public key infrastructure (PKI), including banking, e-commerce, and e-government services.

The software installs a lightweight native component that bridges web pages and local cryptographic services via a browser extension or native messaging, allowing modern, cross-browser operation without legacy plug-ins. It lets users authenticate and sign with personal or corporate certificates stored on a PC, USB token, smart card, or other supported media.

Key capabilities:

• PKI operations: electronic signature, verification, encryption, and decryption
• Certificate lifecycle management: import, export, backup, renewal, and revocation checking
• Support for multiple storage media and hardware cryptographic devices
• Secure communication between the browser and local cryptographic modules
• Automatic updates and options suitable for enterprise deployment

Typical environments include Windows and macOS desktops using Chrome, Edge, and other modern browsers. Some protected sites may prompt installation or updates of SecuKit NX when needed. The application runs in the background and starts on demand; removing it may affect access to services that require certificate-based authentication in Korea.
