### Parameters

* **Type** *\<unquoted string> -* The type of checksum that the user wants to perform. The possible values for this parameter are: *MD5*, *CRC32* or *dynamic*.
* **Source Type** *\<unquoted string> -* The type of source that the user wants to calculate the checksum. The possible values for this parameter are: *File*, *Text* or *dynamic*.
