I would like to zip and unzip my files with a password if possible, I am not sure ! Thanks.

                if let compressedData = html.data.gzip() {
                    try compressedData.write(to: filePath)
                }

Encryption is not supported by this library. But it is of course possible to add encryption after compression. Maybe you can find what you need here: https://developer.apple.com/documentation/cryptokit/performing_common_cryptographic_operations

Just for info, compression should be performed before encryption. If not, the high entropy of encrypted data streams will cause a very poor compression rate, regardless of which compression algorithm you use.
