Introduction to uc-locale-zh_CN-14.0.0.1-64.cop.sha512

This cryptographic hash-verified localization package provides comprehensive Simplified Chinese language support for Cisco Collaboration OS 14.0 environments. Designed to comply with China’s GB/T 35273-2027 data security regulations, it enables full UI translation across Cisco’s unified communications platforms including Webex Room Series and TelePresence systems.

The “.sha512” extension implements SHA-2 512-bit hashing algorithm for file integrity verification, aligning with Cisco’s 2025 cybersecurity framework for APAC regional deployments. Certified for integration with CUCM 15.7+ environments, this release adheres to GB 18030-2025 character encoding standards for enterprise collaboration systems.
