No answer because ti is an irrelevant side track. The issue is that
many of you have said my algorithm must be 'weak' 'amateur'etc. I
have been told that "any script kiddy could break it"...I have been
called "jackass", "dumbass", etc. Some people have done frequency
analysis, some have tried monoalphabet substitution or xoring. I have
posted a site with a plain text sample, the key and three other
samples....

Plenty of information to crack it...and you are all so sure its easy
to crack, but noone does....
