<hash type> is the type of hash value you want returned (Required):

Changed:

<

B for a 64 byte binary value

>
>

BIN for a 64 byte binary value

UC for a 128 byte readable value, upper case

Editorial comment: This API provides a great way to overcome the APPX 256-character key length limitation. If your desired key is a field longer than 256 (such as a server file path or a group of many fields), or if it will be longer than 256 when the primary key is appended, pass the desired key value into this subroutine and use the resulting 128-byte value as your guaranteed unique key.
