This probably has a big hole in it that I missed. But I just feel there must be some way to make a PK cryptosystem using Chinese Remainder Theorem. And I've found it in this one way at least.

I'm somewhat concerned this is simply the (already broken) Knapsack PK cryptosystem, but I don't know enough about that to say if it's different or not, essentially. Anyway, I know this community is not totally deep into reviewing crypto from random people, but I'm putting it out here as a record and in case anyone sees a hole the care to point out. Thanks!
