A common format for compressing data. It’s used by a large number of applications for the exchange of data, back-ups and file compression. In ZIP archives they use various compression algorithms. The cryptographic algorithm is proprietary, so confidential data is better stored in an archive with a more complex protection system (RAR, 7z, etc.).
This is one of the most common file compression formats. It was created by Russian programmer Evgeny Roshal. The format allows one to break up an archived file into several parts, to block an archive to prevent accidental modification, and to enhance data recovery (helps to renew a damaged archive). It has a 128-bit AES algorithm.
