Ruby 3.0 exposes hooks for blocking operations and Async can handle them.
If you want to write something which is based on async, use Async::Queue. Otherwise, if you want to use thread primtives, use them. But if you mix it, and expect concurrency, you better use Ruby 3.
In other words, if you use thread primitives with async on Ruby 2, you will block the reactor.

2) шифровать имена файлов внутри архива?
If archive headers are not encrypted (“encrypt file names” option is disabled), file checksums for encrypted RAR 5.0 files are modified using a special password dependent algorithm. This prevents third parties from guessing file contents based on checksums.
What is the "Encrypt File Names" Option?https://www.win-rar.com/encryption-faq.html?&L=0
If you set the "Encrypt file names" option, WinRAR will not only encrypt the file data, but all other sensitive archive areas like file names, sizes, attributes, comments and other blocks. This provides a higher level of security.
If you want to prevent third parties from drawing conclusions about the content of the archives based on the meta files, you should enable this function. Without entering the correct password, it is impossible to even view the list of files that have been encrypted.
