uploadPartSecurely

public UploadPartResult uploadPartSecurely(UploadPartRequest req)
                                    throws CosClientException,
                                           CosServiceException

NOTE: Because the encryption process requires context from block N-1 in order to encrypt block N, parts uploaded with the COSEncryptionClient (as opposed to the normal COSClient) 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 COSCryptoModule

Throws:

CosClientException

CosServiceException

public PutObjectResult putInstructionFileSecurely(PutInstructionFileRequest req)

Specified by:

putInstructionFileSecurely in class COSCryptoModule

Returns:

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