I don't know what the reason for the error is, whether it's an application bug that Microsoft expects, or whether it's a logic bug in rsaenh.
It appears that the app is just broken. According to tests I'm writing, nearly all Windows versions fail with this key too: only NT4 incorrectly doesn't check the size of the input buffer. What version of Windows did you try this on?
