You can purchase the KMS service in the following ways:
Purchase the service on the KMS overview page at Tencent Cloud official website.
Log in to the KMS Console and purchase the service.
Note:
KMS can be seamlessly integrated with Tencent Cloud services such as COS, CBS, TDSQL, and CFS for encryption. You need to activate KMS first before you can use KMS-related encryption features for those services.
