Pull request overview
This PR introduces a new hsm/ area to the examples repository, adding a DTLS client example that demonstrates using wolfHSM as the cryptographic backend (keeping private key operations on the HSM), and wires the new area into the top-level documentation.
Changes:
- Added a new
hsm/documentation entry and anhsm/README.mdlanding page for wolfHSM-related examples. - Added a DTLS client example (
hsm/dtls_client/) including build/run tooling (Makefile) and required wolfSSL/wolfHSM configuration headers. - Implemented a DTLS client that offloads ECC signing to wolfHSM via PK callbacks.
