I have a new client who I am sending data too in a zip file format. I sent
him a file compressed using WinZip AES encryption (Encryption property = 4).
His un-encryption package (7-Zip) does not seem to support this. I am
forwarding you his request.
I know nothing about encryption and hope you can recommend the necessary
‘Encryption property to use with Chilkat to be compatible with his package.
7-Zip version 4.42 does not support WinZip AES Encryption. You can use
the older (less secure) Zip 2.0 Encryption (also known as Password Protection) by
instead setting the Encryption property = 0, and the PasswordProtect property = true.
