Hello. I just posted an encryption program on the web. It uses a key-
generated pseudorandom stream of characters that get XORed with the
plaintext to produce the cyphertext. For decryption, the same stream
is run against the cyphertext. (Such is the nature of the XOR
operation.) You can download the program at:
http://www.brigadoon.com/~semprini/3dmx
I am interested in other people's views, comments, questions, etc. on
this program. Any questions, comments, etc. can be sent to me at
"semprini@theschool.com".
Thanks,
Dylan

Why do peaple keep posting examples of this lame cryptosystem? I mean how
meany examples of XOR with the output of a pydorandom strame do we have to
see?
Semprini please find some good books on Crypto (and read the sci.crypt
FAQ) to see why what you have done is week.
