Key Management Service (KMS)
-
Key Management Service (KMS) is a secure, reliable, and easy-to-use cloud service that helps users create, manage, and protect keys in a centralized manner. It uses Hardware Security Modules (HSMs) to protect keys. All the keys are protected by root keys in HSMs to avoid key leakage. KMS implements access control and log tracking on all operations on keys, and provides the usage records of all keys to meet audit and compliance requirements.
Available in all regions.

Importing a Key
-
A CMK contains key metadata (key ID, key alias, description, key status, and creation date) and key materials used for encrypting and decrypting data. If you want to use your own key materials instead of the KMS-generated materials, you can import your key materials to KMS on the console. CMKs created using imported materials and KMS-generated materials are managed together by KMS.
Available in all regions.
