Yes, it does.
The way I like to think of such a scheme is to consider the secret algorithm itself to be the key, which then drives the cryptosystem composed of the CPU instruction sequencer on the encrypting machine. Thus all messages are encrypted with the same key; it should be easy to see why that isn't secure. ______c_____________________________________________________________________ Mike M Nally * Tiv^H^H^H IBM * Austin TX * I want more, I want more, m5@tivoli.com * m101@io.com * I want more, I want more ... <URL:http://www.io.com/~m101> *_______________________________
