Even if the ZIP algorithm was secret, are you saying that it would be
useful cipher? So if the ZIP algorithm was ever known, then everyone
who used it on the entire planet would be compromised. WOW! That's a
real nice crytpo system.

I think your missing one of the most basic principles of cryptographic
security. Likelihood of a compromise rises proportionally to the
number of people who know the secret key. You NEVER use a shared key.
