If you bang in a long string of "A" chars and use a string of "A" chars 
as the key, then try using the same length string of "B" chars (or "a" 
chars or "H" chars or "-" chars, etc, etc) results in a "decoded" string 
of all the same chars (different ones for each key string, but a decoded 
string of all the same chars and of the right length).

Now, I'm no cryptographer, but I think that's a very unlikely result for 
a strong crypto algo -- the wrong key should produce "random junk" no 
matter what the original input clear text, no?

In case it matters, I used 400 chars input string and 30 chars key -- the 
max encodor allows for both.
