Hi Garpamp and Adrelanos,
I agree with you too!.. as I am not affiliated with BitMail, .. all that is
needed, you request. It seems to be a model like waste.sf.net out as a
reference. The difference maybe is, I tried to evalute it, and we could
share experience. Anyway.., it is definately a p2p
I created a new hand cipher over the past few weeks, and announced it on my
blog yesterday. I'm curious what people on this list think.

The idea comes from taking an 8x8 chessboard, and assigning the values
0-63 randomly and uniquely

the way that you use the plaintext to avoid short cycles (the output number
etc) is worrying - it might open you up to a chosen plaintext attack in some
way.
replying to myself, sorry (but at least not top-posting this time) i

Maybe it's just me, but the soup to nuts cryptanalysis process is
black magic. So I am curious...does one start with side channel
attacks? Which attacks are tried on an algorithm first and how is that
decided?

first, remove the complicated edge rules. instead, imagine that the
board repeats. so something leaving nort from h4 will arrive at a7.
this might help remove biases from the

you don't have to reverse it (unless i am confused)! that's the beauty of a
stream cipher. encryption and decryption are the same, except you remove the
random stream instead of adding it.
Ah, yes. I'm not thinking clearly. I was
