Scenarios

Sensitive Data Encryption

Sensitive information encryption is a core capability of KMS, mainly used to protect sensitive data (less than 4 KB) on the server disks such as keys, certificates and configuration files.

Envelope Encryption

Envelope encryption is a high-performance encryption and decryption solution for massive amounts of data. With the aid of envelope encryption in KMS, only the data encryption keys (DEKs) need to be transferred to the KMS server (which are encrypted and decrypted with the CMK), and all data is processed with efficient local symmetric encryption which has little impact on user access.
