Tizen Native API  6.0
Key Manager Client

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.

key_type in key may be set to CKMC_KEY_NONE as an input. key_type is determined inside key manager during storing keys.
Some private key files are protected by a password. If raw_key in key read from those encrypted files is encrypted with a password, the password should be provided in the ckmc_key_s structure.
If password in policy is provided, the key is additionally encrypted with the password in the policy.
