问题
I am trying to write a utility using aws-java-sdk (1.11.230). I am able to write a file with SSE-KMS by using PutObjectRequest as follow:
PutObjectRequest putRequest = new PutObjectRequest(existingBucketName, keyName, file)
.withSSEAwsKeyManagementParams(kmsKeyId);
but while trying to upload it in multipart, I could not find any way to specify encryption configuration for SSE-KMS.
Could anyone please suggest a way to go through this successfully. Any suggestion will be appreciated.

Finally, I am able to find the solution for this. It can be done by setting headers to InitiateMultipartUploadRequest object as follow:
InitiateMultipartUploadRequest initRequest = new
InitiateMultipartUploadRequest(bucketName, keyName);
initRequest.putCustomRequestHeader("x-amz-server-side-encryption", "aws:kms");
initRequest.putCustomRequestHeader("x-amz-server-side-encryption-aws-kms-key-id", kmsKey);

Can also be done like this:
InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest("example-bucket", "textfile.txt"); SSEAwsKeyManagementParams kms = new SSEAwsKeyManagementParams("KMS-key-alias");
initRequest.setSSEAwsKeyManagementParams(kms);
initResponse = s3Client.initiateMultipartUpload(initRequest);
