According to Perry E. Metzger:
Sadly, the Friedmans already cracked the "multiple repeating xored keys" cypher a while back -- about fifty years ago.
I knew it was crackable. That wasn't the point. The point was data hiding.
Don't be embarassed, by the way -- everyone comes up with cyphers that have been cracked before. However, I would suggest reading "The Codebreakers" and the current literature before proposing new systems.
I'm not embarassed; I didn't develope the crypto I was discussing. I was simply discussing a new application for it. I will read Codebreakers.
