It hashes files with BLAKE2 implementations and occupies the same command-line niche as tools such as `sha256sum`, but for BLAKE2. ### Projektgeschichte BLAKE2 is a cryptographic hash function family derived from the BLAKE SHA-3 finalist lineage. The official BLAKE2 repository packages portable C implementations, optimized implementations for several CPU families, benchmark code, and the `b2sum` command-line utility. The `b2sum` source file carries a 2012 copyright notice for the BLAKE2 reference source package, and the BLAKE2 specification was later published as RFC 7693 in 2015. The repository's sparse tag history reflects a small reference-code package rather than a continuously shipped application. ### Adoptionsgeschichte `b2sum` adoption is tied to users who want a standalone BLAKE2 checksum utility from the reference implementation. The input package facts list Homebrew, Nix, and Scoop packages, which is typical for small cryptographic command-line utilities that package managers make easy to install across platforms. The broader BLAKE2 family became notable because it offered high performance while retaining cryptographic-hash use cases. For CLI users, `b2sum` is the simple artifact: install a tiny package, hash files, and compare output in scripts. ### Wie es verwendet wird `b2sum` reads files and emits BLAKE2 digests for verification or scripting. The source notes compatibility concerns with coreutils-style checksum behavior, which explains the familiar package-manager naming and command-line shape. There is no project-level configuration file or credentials file; `b2sum` is a stateless local hashing utility. ### Warum Paket-Nerds sich dafür interessieren For package nerds, `b2sum` is the satisfying opposite of a cloud CLI: tiny, C-based, stateless, and useful anywhere checksums are useful. Its main packaging questions are license expression, CPU-optimized source selection, and making the reference utility available without pulling a larger suite. It also shows how package names can be misleading beside cloud tooling: `brew:b2sum` is BLAKE2 checksum software, not related to Backblaze B2. ### Zeitleiste - 2012: The BLAKE2 reference package includes the `b2sum` tool source. - 2015: RFC 7693 publishes the BLAKE2 cryptographic hash specification. - 2016: The BLAKE2 repository has a public `20160619` tag. - 2019: The BLAKE2 repository has a public `20190724` tag. ### Related projects - BLAKE2b and BLAKE2s are the main BLAKE2 hash variants in the reference package. - BLAKE was the SHA-3 competition finalist lineage from which BLAKE2 descends. - `sha256sum` and other coreutils-style checksum tools are the closest command-line analogs. ### Quellen - BLAKE2 official website - BLAKE2/BLAKE2 README and b2sum source - RFC 7693 - source_facts.package-manager ## Sicherheitshinweise Für b2sum wurde kein passendes lokales Secret-Handling-Manifest gefunden.
