Random is not an option. If we use random string, how will we get the
right attachment path on a second call? This function must return the
same value given the same input.
Having said that, I do agree (taking into account the other comment)
that md5 may not be a very good idea. Maybe simply something like
"__/id". Ideally, we should be able to recover the original id from the
path to attachment.
Best,
Ihor
