Encryption Example Of Uploading

Bucket.PutObjectInput putObjectInput = new Bucket.PutObjectInput();

putObjectInput.setXQSEncryptionCustomerAlgorithm("AES256");
putObjectInput.setXQSEncryptionCustomerKey("key");
putObjectInput.setXQSEncryptionCustomerKeyMD5("MD5 of the key");
putObjectInput.setBodyInputFile(new File("file path"));

Deciphering Example Of Downloading

When download the file has been encrypted, you need decipher it like the codes below.

Bucket.GetObjectInput putObjectInput = new Bucket.GetObjectInput();

putObjectInput.setXQSEncryptionCustomerAlgorithm("AES256");
putObjectInput.setXQSEncryptionCustomerKey("key");
putObjectInput.setXQSEncryptionCustomerKeyMD5("MD5 of the key");
Bucket.GetObjectOutput output = bucket.getObject("your-object-name", putObjectInput);
