Use two hash functions and concatenate the hashes. While both
hash systems may eventually be hacked it is unlikely that hacking
them will result in a targeted alias.
Just make it possible to change the hash in the future.
I'm thinking about mail_attachment_hash setting where you can
configure it pretty much any way you want.
Have a utility that updates all (or a subset) of them.
That won't be necessary. Once the hash changes, the new files are
created with new hash function and it doesn't matter if the old hash
is broken because you can't generate new files with it anymore
anyway.
Won't files hashed with the old function begin to dupe though?
