It provides APIs accessing on the secure repository and additional secure cryptographic operations.

Required Header

#include <ckmc/ckmc-manager.h>

Overview

It provides APIs for storing, getting, and removing APIs for keys, certificates, and sensitive data on/from the Key Manager secure repository which is protected by a user’s passwords. Additionally, it provides secure cryptographic operations for non-exportable keys without revealing key values to clients.
