Password-protected archives

## What would you like to have changed?

It's necessary to obtain a stream file inside of password-protected archive.

## Why is this feature a useful, necessary, and/or important addition to this project?

To obtain a stream file inside a password-protected archive, you now need to extract it using third-party tools.

## What alternatives are there, or what are you doing in the meantime to work around the lack of this feature?

I'm using C# language tools.

## Please link to any relevant issues, pull requests, or other discussions.

I don't have this one.

The issue does not name files, tests, archive formats, or an API entry point. Start by reviewing the library’s existing archive extraction interfaces and determining which password-protected formats must be supported. Done means obtaining a stream for a file inside a password-protected archive without third-party extraction tools.
