NOTE: Because the encryption process requires context from block N-1 in order to encrypt block N, parts uploaded with the AmazonS3EncryptionClient (as opposed to the normal AmazonS3Client) must be uploaded serially, and in order. Otherwise, the previous encryption context isn't available to use when encrypting the current part.

Throws:

AmazonClientException

AmazonServiceException
