Create a password-protected .zip containing a single file. (This uses the older Zip 2.0 encryption scheme, which is weaker and not as secure as AES encryption, which Chilkat Zip also supports.)

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.
