What is cn-north-1-KMS-Keys?

Last updated: January 09, 2025

Each AWS KMS key that you create in AWS KMS costs $1/month (prorated hourly). The $1/month charge is the same for symmetric keys, asymmetric keys, HMAC keys, multi-Region keys (each primary and each replica multi-Region key), keys with imported key material, and KMS keys with a key origin of either AWS CloudHSM or an external key store (XKS). For KMS keys that you rotate automatically or on demand, the first and second rotation of the key adds $1/month (prorated hourly) in cost. This price increase is capped at the second rotation, and any subsequent rotations will not be billed.

This specific billing code is related to the China region in Beijing.

The postfix represents the instance type, cn-north-1-KMS-Keys.

It belongs to the Encryption Key category of service awskms.
