Calculates a hash code using binary data and a hash algorithm b. The binary data is created from a text a and a charset d. To increase the readability it's possible to specify a text c being used as the separator between the hash values.

Using an invalid charset or an unsupported hash algorithm leads to an error aborting the mapping.

Parameters

Parameter	Description
a	The text to calculate the hashcode from.
b	(optional) The hash algorithm to be used. Default: "md5".
c	(optional) The separator between the values. Default: No separator.
d	(optional) The encoding to be used for the generation of bytes from the text. Default: "utf8".

Because the Euro sign is not part of encoding "8859_1", it is replaced by a question mark, leading to the effect that two different texts result into the same hash value.
