Introduction to JabberSDK11EAP1.zip

This software development kit enables enterprise-grade customization of Cisco Jabber clients through Extensible Authentication Protocol (EAP) integration. Released in Q2 2025 as part of Cisco’s collaboration platform modernization initiative, Version 11.1 introduces quantum-resistant encryption workflows and enhanced Microsoft Teams interoperability features.

The SDK specifically supports:

  • Custom authentication module development for zero-trust environments
  • Multi-vendor UC system integration through standardized APIs
  • Compliance with FIPS 140-3 cryptographic validation requirements

Core Technical Capabilities

​​1. Enhanced Security Framework​​

  • Pre-configured CRYSTALS-Kyber quantum-safe encryption templates
  • TLS 1.3 cipher suite rotation mechanisms with 5-minute intervals
  • Hardware Security Module (HSM) integration for key management

​​2. Cross-Platform Integration​​

  • Native Microsoft Teams message threading preservation
  • Webex App Hub service discovery templates
  • CUCM 15.5+ backward compatibility modes

​​3. Developer Productivity Tools​​

  • XML configuration templates for 50+ Jabber parameters
  • Automated API documentation generator
  • Real-time debugging console with packet capture
