nokia/CMPclient-embedded-lib

This project is a legacy utility library that has seen almost zero community engagement (4 stars) and no active development (0.0 velocity) despite being over 8 years old. While it carries the Nokia name, it appears to be a 'code drop' of a specific internal requirement rather than a living open-source project. In the modern IoT landscape, CMP (Certificate Management Protocol) is often bypassed in favor of simpler protocols like EST (Enrollment over Secure Transport, RFC 7030) or platform-specific provisioning tools from AWS IoT and Azure IoT Hub. The technical moat is non-existent; any firm needing CMP on Mbed TLS would likely write their own implementation or use a more maintained library like wolfSSL or the CMP support added to OpenSSL 3.0. Its niche focus on constrained devices is its only merit, but the lack of updates for KUR/KUP (Key Update) functionality, which was mentioned as a future goal 8 years ago, indicates the project is effectively dead.
