You can't reverse a hash and to generate a new hash the code needs the
password for the user in plain.

Well, to be fair, the change to SHA-1 is because you can "reverse"
MD5 all too easily (where reverse just means that you find something
which hashes to a given hash, which hasn't to resemble your original
password all too much). Usually you want this something to have
some properties to be useful.

But I don't think your operating system is going to do that behind
your back ;-)

Not if it's Linux, anyway...
