This fork add support for Standard Zip Encryption.
The work is based on https://github.com/alexmullins/zip
Available encryption:
zip.StandardEncryption
zip.AES128Encryption
zip.AES192Encryption
zip.AES256Encryption
Zip Standard Encryption isn't actually secure. Unless you have to work with it, please use AES encryption instead.
