CFZip has been in ColdFusion since CF8 but it was only for unencrypted zip files. ColdFusion Splendor brings password protection to CFZip with multiple encryption methods. 2 new attributes have been added to CFZip and CFZipParam to support this functionality.
Password
EncryptionAlgorithm <Standard, AES-128, AES-256 (default)>
Examples

cfzip(action=”list”, name=”zipFileList”, file=”C:ZipTesttestzipfile.zip”);
cfzip(action=”unzip”, file=”C:ZipTesttestzipfile.zip”, destination=”C:ZipTest”, password=”pass”, overwrite=”true”);
