This function calculates a checksum for file a by using hash algorithm b. To increase readability, separators c can be specified between the individual values when generating the checksum. See examples.

The function supports all algorithms that are supported by the Java Virtual Machine.

Parameters

Parameter	Description
a	Filename with path.
b	(optional) The hash algorithm to be used. Default: "MD5". Note: Use the three dots to select a value.
c	(optional) The separator between the values. See examples. Default: <empty>.
d	(optional) If "true", the hash code is returned as a Base64-encoded string. This functionality is necessary when connecting to Amazon web services, for example. Default: "false".
