cfv is a utility to test and create a wide range of checksum verification files. It currently supports testing and creating sfv, sfvmd5, csv, csv2, csv4, md5, bsdmd5, sha1, sha224, sha256, sha384, sha512, torrent and crc files. Test-only support is available for par, par2.
cfv was originally written by Matthew Mueller (original project home). This is a friendly fork of cfv maintained by David Gnedt.
Python ≥ 2.7 – older versions might work, but are unsupported. Python 3 is not supported yet, see issue #8.
- Python Imaging Library (PIL) or Pillow – only needed if you want to create the dimensions column of .crc files.
- python-fchksum – may speed up checksumming speed a bit, especially if your python was not built with the mmap module.
You can get the latest releases via the Python Package Index (PyPI) or from the Github releases page. Other distribution ways are work-in-progress, see issue #4.
If you have a working Python installation with pip, you can follow these installation steps:
pip install cfv- read man page
man cfvor read usagecfv -hand have fun☺️
Download a snapshot from the Github releases page or checkout the development version via Git.
python setup.py install- read man page
man cfvor read usagecfv -hand have fun☺️ - optional: run tests to verify correct operation:
cd test; ./test.py
