history
Project history and usage
md5sha1sum is a small Microbrew toolset providing md5sum, sha1sum, and ripemd160sum replacements. The official page says the tools were intended as compact drop-in replacements for GNU textutils hash utilities, especially for systems such as Solaris where installing all of textutils was excessive.
Project history
The official Microbrew page lists releases from 0.9.0 on 2004-07-31 through 0.9.5 on 2006-12-06. It presents the package as a lightweight portability utility for Linux, Solaris 7 through 10, and Mac OS X, with OpenSSL 0.9.6 or newer as its only listed dependency.
The project is distributed from the official homepage as source tarballs rather than through an official source-control repository. That matches its early-2000s package style: a small tarball, README, INSTALL, ChangeLog, and checksums on a simple project page.
Adoption history
The supplied package-manager metadata shows Homebrew and MacPorts packaging md5sha1sum. Its adoption appears narrow but useful on macOS-oriented package managers, where GNU-compatible checksum command names were historically less universal than on GNU/Linux.
Because only the official Microbrew page and package-manager metadata are available here, broader adoption claims should be kept modest.
How it is used
The official page describes the tools as drop-in replacements for md5sum, sha1sum, and ripemd160sum. In practice the package is for shell scripts and users that want familiar checksum commands without installing the larger GNU textutils/coreutils set.
Homebrew's recorded executable for this formula is `ripemd160sum`, while the upstream page documents the full md5sum, sha1sum, and ripemd160sum toolset.
Why package nerds care
md5sha1sum is a package-nerd artifact from the era when Unix variants differed sharply in which GNU-style checksum tools were present by default. Its purpose was not novelty but portability: providing the familiar hash commands in a tiny OpenSSL-backed package.
The package is also a reminder that package managers preserve small compatibility utilities long after the surrounding platform defaults have changed.
