AmazonServiceException

abortMultipartUploadSecurely

public void abortMultipartUploadSecurely(AbortMultipartUploadRequest req)

Specified by:

abortMultipartUploadSecurely in class S3CryptoModule<MultipartUploadContext>

initiateMultipartUploadSecurely

public InitiateMultipartUploadResult initiateMultipartUploadSecurely(InitiateMultipartUploadRequest req)
                                                              throws SdkClientException,

AmazonServiceException

uploadPartSecurely

public UploadPartResult uploadPartSecurely(UploadPartRequest req)
                                    throws SdkClientException,
                                           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.

uploadPartSecurely in class S3CryptoModule<MultipartUploadContext>

Throws:

SdkClientException

public void putLocalObjectSecurely(UploadObjectRequest req,
                                   String uploadId,
