PKWare is offering a free license for a crippled version of SecureZIP
. Don't know how long the offer lasts. The few grayed-out features seem to be related to public/private assymmetric ciphers: Digital signing, etc.
Archive creation and encryption is fully supported. You wouldn't notice the missing features if the come-ons weren't so obvious. And if you do need those, you'll probably be looking at GNU Privacy Guard
One caveat: SecureZIP silently, presumptuously and immediately (when first run) takes over all file associations it knows about, including ZIP. WinZip users take note!
WinZip 11.0 already offers most of this stuff, and it mentions digital signing (without showing you the grayed-out crippled buttons). On the other hand SecureZIP has snazzy modern icons.
I don't recommend any of this, of course. You need to keep track of passwords, to maintain access to your files. A touchy proposition, as the tickings and the tockings pile up, and your neurons quietly expire under the relentlessly calm assault of daily entropy. Personal encryption protocols become tedious very quickly, so unless you need
this stuff, you're far better off to avoid it.
