+## checksum_algorithm
+
+AWS allows to calculate the integrity checksum server side. The additional checksum is
+used to validate the data during upload or download. The following 4 SHA and CRC algorithms are supported:
+
+* CRC32
+* CRC32C
+* SHA1
+* SHA256
+
+For more info refer to [object integrity](https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html).
