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. ### Timeline - 2004-07-31: md5sha1sum 0.9.0 released. - 2004-08-03: md5sha1sum 0.9.2 released. - 2006-12-05: md5sha1sum 0.9.4 released. - 2006-12-06: md5sha1sum 0.9.5 released and listed as latest on the official page. ### Related projects - The official page positions md5sha1sum as an alternative to GNU textutils hash utilities. - OpenSSL is listed as the package dependency. ### Sources - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** md5sha1sum - **Version Scheme:** 0 - **Revision:** 1 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** yes - **URL Keys:** stable ## Other Package-Manager Records - MacPorts - md5sha1sum: normalized package name match | MacPorts ports tree: sysutils/md5sha1sum/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Security and crypto packages](https://www.automicvault.com/pkg/security-crypto-tools/) - Matched security, identity, cryptography, password, signing, or certificate metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [openssl@4](https://www.automicvault.com/pkg/brew/openssl-4/) - Runtime dependency declared by Homebrew. - [md5deep](https://www.automicvault.com/pkg/brew/md5deep/) - Shares av.db curated category or tags: checksums, cli, cryptography, hashing, security. - [rhash](https://www.automicvault.com/pkg/brew/rhash/) - Shares av.db curated category or tags: checksums, cli, cryptography, hashing, security. - [sha1dc](https://www.automicvault.com/pkg/brew/sha1dc/) - Shares av.db curated category or tags: cli, cryptography, hashing, security, sha1. - [nettle](https://www.automicvault.com/pkg/brew/nettle/) - Shares av.db curated category or tags: cli, cryptography, hashing, security. - [sha2](https://www.automicvault.com/pkg/brew/sha2/) - Shares av.db curated category or tags: cli, cryptography, hashing, security. - [sha3sum](https://www.automicvault.com/pkg/brew/sha3sum/) - Shares av.db curated category or tags: cli, cryptography, hashing, security. - [aescrypt](https://www.automicvault.com/pkg/brew/aescrypt/) - Shares av.db curated category or tags: cli, cryptography, security. - [aespipe](https://www.automicvault.com/pkg/brew/aespipe/) - Shares av.db curated category or tags: cli, cryptography, security. - [jscrypto](https://www.automicvault.com/pkg/npm/jscrypto/) - Security-sensitive metadata or terminology overlaps.
