Hi there,

we try to use archive-zip and set password for my-zip as a following code below

Archive::Zip.archive( File.join(zip_name), File.join(file_path, file_name), encryption_codec: Archive::Zip::Codec::TraditionalEncryption, password: file_name.gsub(/.csv/, '') )

actually, i dont know what TraditionalEncryption is?

and how can I use AES-256 encryption?

thanks in advance.

Traditional encryption is a rather weak encryption codec that is the first one supported in ZIP files as I recall. Unfortunately, I never got around to adding the more interesting codecs; however, this library is plugable (you can write your own codec class and use it with the encryption_codec parameter), and I'm also willing to take PRs to add additional functionality.
