NOTE: The PKCS #11 library and documentation are part of the FreeRTOS LTS Roadmap. These libraries are fully functional, but undergoing optimizations or refactoring to improve memory usage, modularity, documentation, demo usability, or test coverage. They are available on GitHub or part of the LTS Development Snapshot download
PKCS #11 Library
IntroductionPKCS #11 is a standardised and widely used API for manipulating common cryptographic objects. It is important because the functions it specifies allow application software to use, create, modify, and delete cryptographic objects, without ever exposing those objects to the application’s memory. For example, FreeRTOS IoT reference integrations use a small subset of the PKCS #11 API to, among other things, access the secret (private) key necessary to create a network connection that is authenticated and secured by the Transport Layer Security (TLS) protocol – without the application ever ‘seeing’ the key.
PKCS #11 is maintained by the OASIS PKCS#11 Technical Committee.
