Please don't commit a new interface when my initial question has not
been answered. What is this interface supposed to solve? This is
essential as a password verification interface very naturally can
internalize all storage necessary for the different backends where as a
contract that involves returning a "decrypted" string can not. For the
same reason, the interface contract here is completely wrong. There is
no need to expose the internals like this. The only non-thread-safe
space used by crypt(3) that should ever be exposed is the space
necessary for the return storage.
