RPM to ZIP Converter

The RPM (RPM Package Manager, formerly Red Hat Package Manager) file format is a binary package system used primarily by Red Hat-based Linux distributions (RHEL, Fedora, CentOS) to distribute software. Conforming to the Linux Standard Base (LSB), an RPM file consists of a lead, a signature, a header, and a payload. The payload is a cpio archive compressed with GZIP, XZ, or LZMA. The header contains metadata such as dependencies, version numbers, and architecture specifications, indexed by a localized Berkeley DB to manage software installation and updates efficiently.

RPM files are intended to be installed via package management systems like rpm or dnf on Linux. For extraction purposes without installation, the rpm2cpio command-line tool can convert the package into a cpio archive, which can then be extracted. On Windows, 7-Zip supports opening RPM files as archives, allowing users to browse and extract the contained file structure and metadata without executing the installation scripts.

The ZIP format is an archive file format capable of lossless data compression, originally created by Phil Katz of PKWARE. It utilizes a Central Directory structure to catalog files and supports various compression algorithms, most notably DEFLATE (RFC 1951). The format is standardized under ISO/IEC 21320-1:2015 as a document container file and serves as the base structure for modern file types like .docx and .jar.

The ZIP format enjoys universal native support across all major operating systems, including Windows (File Explorer), macOS (Archive Utility), and Linux. No third-party software is strictly required for basic extraction, though power users often employ tools like 7-Zip or WinRAR to access advanced features like AES-256 encryption or multi-volume spanning.
