# cfv – Command-line File Verify
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](http://cfv.sourceforge.net/)).
This is a [friendly fork of cfv](https://github.com/cfv-project/cfv) maintained by Lisa Gnedt.

## Requirements
Python ≥ 3.7 – older versions might work, but are unsupported.
For Python 2 support, see the [python2 branch](https://github.com/cfv-project/cfv/tree/python2).
### Optional
* [Python Imaging Library (PIL)](https://www.pythonware.com/products/pil/) or
[Pillow](https://python-pillow.org/) – only needed if you want to create the
dimensions column of .crc files.
## Install
You can get the latest releases via the [Python Package Index (PyPI)](https://pypi.org/project/cfv/)
or from the [Github releases page](https://github.com/cfv-project/cfv/releases).
Other distribution ways are work-in-progress, see [issue #4](https://github.com/cfv-project/cfv/issues/4).
### From PyPI
If you have a working Python installation with pip, you can install via PyPI:
```sh
pip install cfv
```
### From Source
Download a snapshot from the [Github releases page](https://github.com/cfv-project/cfv/releases)
or checkout the development version via Git.
```sh
pip install .
# optional: run tests to verify correct operation
cd test; ./test.py
```
### From OS-specific Repositories
#### Arch Linux
To install the development version from [AUR](https://aur.archlinux.org/packages/cfv-git) (maintained by @vestingz):
```sh
yay -S cfv-git
```
#### FreeBSD
A FreeBSD port is available (maintained by @Terry-Kennedy).
To install the pre-built package (updated quarterly, so may be out-of-date):
```sh
pkg install cfv
```
To build from source (make sure your source tree is up-to-date via any of the usual methods):
```sh
cd /usr/ports/security/cfv
make; make install; make clean
```
To update the pre-built package:
```sh
pkg upgrade cfv
```
To update from source (again, make sure your source tree is up-to-date):
```sh
portupgrade cfv
```
#### NixOS
To use the latest version included in [nixpkgs](https://search.nixos.org/packages?channel=unstable&show=cfv) (maintained by @jjtt):
```sh
nix-shell -p cfv
```
## Usage
Please read the man page `man cfv` or the usage `cfv -h` and have fun ☺️
## Contributions
Contributions are welcome, just open a pull request ☺️
## Alternative Tools
Here is a community-compiled list of alternative tools that cover some of cfv's functionality (without warranty):
* GNU coreutils \*sum: md5sum, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, ...
* cksfv
* [rhash](https://github.com/rhash/RHash) (with `-rc` does more or less the same thing as cfv, performance is good and it supports most hash formats including bittorrent. It lacks cfv's `-m` though.)
* aria2c (to verify torrent checksums)
* bsdsfv (limited to 1024 files for some reason)
* pure-sfv (doesn't seem to display progress information, even with `-v`)
* [bcfv](https://github.com/jarppiko/bcfv) (a Bash frontend to checksum programs (SHA, Blake3, MD5))
