 You may use the S3 server-side encryption functionality via the optional `sse` and `sseKms` parameters. Full documentation of these parameters in relation to the S3 API can be found [here] (http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#upload-property) and [here] (http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html). 
 
-`sse` has two valid values: 'AES256' and 'aws:kms'. 'AES256' utilizes the S3-managed key system, while 'aws:kms' utilizes the AWS KMS system and accepts the optional `sseKms` parameter to specify the key ID of the key you wish to use. leaving `sseKms` blank when 'aws:kms' is specified will use the default KMS key. **Note:** *You must instantiate the S3 instance with `signatureVersion: 'v4'` in order to use KMS-managed keys.*
