Re: It's a Shark.

in reply to It's a Shark.

Unless there's a well known and obvious (but not documented here) restriction on the number of characters the machine will take, I think I've found a bug.

Upon giving this the following input:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

(350 characters) I got the following output:

So far so good...., however, attempting to decrypt that gives:

Hmm.

After several other tests it appears that the machine can only return 279 clean alphabetical characters. Obviously since spaces and non-alphabetcial characters are ignored these can make it appear as if more clean characters are coming out, but that's not the case.

What's happening here?

It's taken almost 3 years for someone to spot that :) .. when you work out how the rotors failing to work, I'll dig out a copy of the revised code I wrote two and a half years ago.. I might even get around to making it shark shaped ;) -- Brother Frankus. ¤	[reply]
