AWS Key Management Service (KMS) is a managed service that makes it easy for you to create and control the encryption keys used to encrypt your data. Starting today, you can import keys from your key management infrastructure into KMS, and use your imported keys in all KMS-integrated AWS services and custom applications. This feature gives you greater control over the generation, lifecycle management, and durability of your keys. Import Key could also help you meet your compliance requirements to generate and store copies of keys outside of your cloud provider.
