CA六十 is a digital certificate (CA lock) management platform for electronic bidding. Its core purpose is to solve the management inconvenience caused by multiple physical CA locks across different platforms, improving usage efficiency and enabling remote bidding.
Security-first. The platform leverages digital certificate technology with encrypted communications, strong identity authentication, and operation auditing to ensure bidding processes and CA lock usage are as secure as using a physical device, while avoiding risks of physical device loss.
The platform centrally manages the digital certificates for different bidding platforms. Users don't need to carry multiple physical locks; they can log in, sign, and perform operations from a unified interface using the appropriate certificate, enabling efficient management and use.
Companies frequently involved in multi-site, multi-platform electronic bidding (such as construction, trading, and service sectors) and their bid specialists, business staff, and IT managers—especially organizations with remote work or centralized control needs.
Supported platforms depend on official information. Such platforms typically aim to be compatible with mainstream public resource trading centers and enterprise-internal e-tendering systems.
