Its manual page still carries the older utility's shape: a single command for testing and creating many checksum-file formats. ### 采用历史 The project documents distribution through PyPI and mentions operating-system packaging paths such as Arch Linux, FreeBSD ports, and NixOS. The input package facts also show package-manager entries for Homebrew, MacPorts, and Nix. ### 使用方式 cfv is used to verify that files match checksum manifests and to create manifests in formats including SFV, CSV, CRC, MD5, SHA-family sums, BLAKE3 b3sum files, BitTorrent metainfo files, and test-only PAR/PAR2 files. ### 为什么软件包爱好者会关心 For package and archive maintainers, cfv is interesting because it covers several checksum dialects in one small CLI, including formats that ordinary coreutils checksum commands do not create or parse. ### 时间线 - 2005: The cfv man page was dated 05 Feb 2005. - Python 3 era: The cfv-project fork documents Python >= 3.7 support and points Python 2 users to a separate branch. ### Related projects - The README compares cfv with GNU coreutils checksum commands, cksfv, RHash, aria2c, bsdsfv, pure-sfv, and bcfv. ### 来源 - - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
