RPM to TAR.7Z (T7Z) Converter

RPM (originally Red Hat Package Manager, now a recursive acronym for RPM Package Manager) is a software package management format developed by Red Hat for Linux distributions, first introduced with Red Hat Linux 2.0 in 1995. An RPM file packages compiled software, configuration files, and documentation alongside rich metadata in a structured binary format consisting of a lead (format identifier), a signature header (integrity and authenticity verification), a metadata header (package name, version, description, dependency lists, file checksums, and installation scripts), and a compressed CPIO archive payload containing the actual files. The rpm tool and higher-level managers like YUM and DNF handle installation, upgrade, verification, and removal of RPM packages. One advantage is comprehensive dependency management — RPM packages declare capabilities they provide and require, enabling automatic resolution of complex dependency chains from configured repositories. The built-in verification system is another strength: rpm --verify checks every installed file against stored checksums, permissions, ownership, and timestamps, detecting unauthorized modifications or corruption. RPM serves as the packaging foundation for major enterprise Linux distributions including Red Hat Enterprise Linux, Fedora, CentOS, SUSE, and openSUSE. Alongside DEB, RPM is one of the two dominant Linux packaging formats, underpinning software management for millions of servers and workstations.
