harmony 鸿蒙Key Generation and Conversion Overview
Key Generation and Conversion Overview
Typical key generation operations involve the following:
Randomly create a key object for subsequent encryption and decryption.
Convert external or internal binary data into a key object for subsequent encryption and decryption.
Create a key object based on the specified key parameter for subsequent encryption and decryption.
Obtain the binary data of a key object for storage or transmission.
Obtain the properties of an asymmetric key object for storage or transmission.
The key object can be a symmetric key object (SymKey) or an asymmetric key pair object (KeyPair). The KeyPair object consists a public key (PubKey) and a private key (PriKey).
