The mark of a good encryption algorythm is that it can't be easily cracked
without the password, *even if the attacker knows the algorythm* (which
will eventually be discovered anyway).  So a better test would be to
provide the encrypt function and see if anyone can come up with another
function which would either crack the code or narrow down the list of
possible passwords to the point where a brute-force attack (run through all
the passwords till one works) might be feasible.  I know very little when
it comes to encryption algorythm design, but I recommend the newsgroup
sci.crypt  A while ago I came up with an algorythm and posted it, but was
answered with a humbling cryptoanalysis explaining just how easily it could
be cracked.

You are precisely right, Issac.  Again, I am not a cryptanalyst, but this
is a principle of encryption: count on your passwords, not the secrecy of
your algorithm.  Also, I didn't seem to get encrypt.shr?
