uploadPartSecurely

public UploadPartResult uploadPartSecurely(UploadPartRequest req)
                                    throws AmazonClientException,
AmazonServiceException

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.

Specified by:

uploadPartSecurely in class S3CryptoModule<MultipartUploadContext>

Throws:

AmazonClientException

AmazonServiceException

copyPartSecurely

Returns:

the result of putting the instruction file in S3; or null if the specified S3 object doesn't exist. The S3 object can be subsequently retrieved using the new instruction file via the usual get operation by specifying a EncryptedGetObjectRequest.
