Hi Lucky, RSA has got their Win95 version of SecurPC. That's 128-bit RC4 encryption; maybe 10X the speed of DES. You could encrypt your zip data from Explorer either on demand, or automatically upon exiting WIN95. (It auto-decrypts on startup.) SecurPC doesn't yet have transparent (fully background) crypto, but given the market pressures, it obviously won't be long in coming. SecurPC does have a number of other unusual features that might offset the lack of transparency. My favorite: At least until the next version of ERA;-) RSA's SecurPC permits you to ship data over the US borders encrypted with 128-bit RC4 in a self-extracting file which can be opened by anyone, anywhere -- with the same OS as the sender, and the right (one-time?) password -- even if they don't have a copy of SecurPC. The key, passed out of band, is certainly not up to PKC standards... but for occasional connections, if you duck the dictionary attack, it looks pretty damn sturdy. One-way symmetric-- kinda neat! (Anyone know how it really works? I got a copy of the v1 user's manual from SDTI, where I do a lot of contract work -- but it doesn't really explain the split of functions. I'll have to ask.)
