How To extract password Protect Zip file or Zip file and save folder from zip file inside memory (folder have images)

extractArchiveToDisk will write a memory Archive to disk, and extractFileToDisk will write a decode a file zip to disk, with the password argument:

If the zip is in memory, you can extract it from memory with Archive archive = new ZipDecoder().decodeBytes(bytes, password="...");. Then you can use that extractArchiveToDisk function to write that out to disk.

A big caveat: I don't expect the password support to be very robust.
