Amazon Translate is a neural machine translation service that delivers fast, high quality, affordable, and customizable language translation. Starting today, you can use your own encryption keys from the AWS Key Management Service (KMS) to encrypt data placed in your S3 bucket. Up until now, Amazon Translate used Amazon S3-SSE to encrypt your data. AWS KMS makes it easy for you to create and manage keys, while controlling the use of encryption across a wide range of AWS services and in your applications. AWS KMS is a secure and resilient service that uses FIPS 140-2 validated hardware security modules to protect your keys. AWS KMS is integrated with AWS CloudTrail to provide you with logs of all key usage to help meet your regulatory and compliance needs. The feature can be configured via the AWS Management console or SDK and supports Amazon Translate’s asynchronous batch translation jobs.
