history
Project history and usage
crcany is Mark Adler's suite of programs for computing arbitrary CRCs and generating C code for efficient CRC calculation and combination.
Project history
The madler/crcany repository was created in 2016. Its README describes the project as a definitive reference for computing and combining any CRC with bit-at-a-time, byte-at-a-time, or word-at-a-time algorithms on big- or little-endian architectures.
Adoption history
crcany is specialized infrastructure software rather than a broad end-user CLI. Its package appeal comes from bundling reference CRC definitions, code generation, test tooling, and small executables that can be built with make.
How it is used
The suite can compute CRCs from named catalogue parameters, combine CRCs from byte sequences, and generate .c and .h files for one or more CRC definitions. The README also documents a make test target that checks calculations and generated code against catalogued CRCs.
Why package nerds care
For maintainers and systems programmers, crcany matters because it turns CRC catalogue data into reproducible C implementations and tests. That makes it useful as both a command-line tool and a source-code generator for packages that need exact checksum behavior.
