This shows that the primary input (the string) is not in the center of the Left hand Side of the Icon.
For programming style where this is in a wire, this gives odd layouts.
All of the basic LabVIEW =xxxx (ref, 0, >0, >=0, <0, <=0, NaN etc) the primary input is inline with the primary output.
The optional input (strict Character case) can be connected at te bottom or top (I prefer top).
Another (more major) point is the documentation:
I find this misleading. This functions tests if this is TRUE, it looks to me like I have to make sure the input string is a Valid MD5 string before using this function (creating a chicken-and-egg situation).
I would rewrite this to:
