in thread Reverse MD5

Digest::MD5::Reverse uses online DBs which seem to store large amounts of texts and the corresponding MD5 sums. That is probably the only reasonable way to do this. However, simply appending a random text/date on every text makes this pretty unusable.

    The summer 2008 edition of 2600 has an interesting extension of this: using Google (etc.) to search for the hash and find an original text (password). Apparently a lot of people or systems post this information intentionally or inadvertently. In some limited sense, you don't need the reverse function if Google is mapping the forward function.
