Of course, in terms of encryption this would be utterly stupid.


Please explain what you mean.

For sensitive data, I use either 128-bit AES or 256-bit AES
encryption in Winzip.

Nah, can't be that sensitive.


Actually it is.

When my receipents do not have Winzip they find they can not open
the AES-encrypted zip file. How do I get around this? Is there a
free utility which recipients can obtain in order to only extract
files from my AES-encrypted ZIPs?

7-Zip does so. But please, stop calling the files ZIP files. This
name is commonly reserved for RFC-conformant PKZIP 2.x compatible
files.


7-Zip does not open AES-encrypted files created by Winzip which is
what I am looking for. Try it and see.

Winzip creates its archive files with the ZIP extension and that is
what I am referring to. I don't control what Winzip chooses to use
as an extension. I just refer to it.

It sounds as if you may be bringing here a point about "ZIP" you
could be better off making direct to the authors of Winzip.
