calculate hash or checksum in many formats
This project is maintained by msztolcman
hashfile calculates hashes or checksums in many formats, also verify them.
Default algorithm is sha1. This can be changed by passing argument -a/--algorithm to hashfile, or by calling hashfile with
algorithm name (ie. using symlinks).
hashfile works pretty well with big files, because always read data partially, by default 4MB of data at once (it can be changed using
--max-input-read param).
# simplest call
% hashfile /etc/hosts
sha1: 4f53fb6efebddfdbe989f3bff980cd07ebcdc6bb /etc/hosts
# specify algorithm
% hashfile -a md5 /etc/hosts
md5: 71e875e9d194c18567f48cf9534ed6cf /etc/hosts
# one file, many algorithms
% hashfile -a md5 -a sha1 /etc/hosts /etc/hosts
md5: 71e875e9d194c18567f48cf9534ed6cf /etc/hosts
sha1: 4f53fb6efebddfdbe989f3bff980cd07ebcdc6bb /etc/hosts
# many files, other algorithm for each one
% hashfile -a md5 -a sha1 /etc/hosts /etc/shells

sha1: e0de09cb8797a4d39f89049d74585e815a3c6ceb /etc/shells
# many files, one algorithm
% hashfile -a sha256 /etc/hosts /etc/shells

2.1.5
hashfile works with Python 2.7+ and 3.3+.
Everything is in help :) Just execute:
hashfile --help
Look at result (remember: list of algorithms may vary on your system):
% hashfile --help
usage: hashfile [-h]
[--algorithm {adler32,crc32,md4,md5,mdc2,ripemd160,sha,sha1,sha224,sha256,sha384,sha512,whirlpool}]
[--generate-algo-symlinks] [--check] [--quiet] [--status]
[--warn] [--max-input-read MAX_INPUT_READ]
[FILE [FILE ...]]
Calculate hash of some files
positional arguments:
FILE list of files (stdin by default)
optional arguments:
-h, --help show this help message and exit
--algorithm {adler32,crc32,md4,md5,mdc2,ripemd160,sha,sha1,sha224,sha256,sha384,sha512,whirlpool}, -a {adler32,crc32,md4,md5,mdc2,ripemd160,sha,sha1,sha224,sha256,sha384,sha512,whirlpool}
algorithm used to calculate hash If given more then
one, then use different algorithms for different files
(use first algo to first file, second algo to second
file etc. If there is more files then algorithms, last
algorithm from list is used.
--generate-algo-symlinks
Show aliases for every algorithm handled by hashfile
--check, -c read checksums from the FILEs and check them
--quiet, -q don't print OK for each successfully verified file
--status, -s don't output anything, status code shows success
--warn, -w warn about improperly formatted checksum lines
--max-input-read MAX_INPUT_READ
maximum data size for read at once
Algorithm can be also set from program name (for example call program as sha1
to use sha1 algorithm)
hashfile should work on any platform where Python
is available, it means Linux, Windows, MacOS X etc.
Simplest way is to use Python's built-in package system:
pip install hashfile
Using pipsi
pipsi install hashfile
Using sources
Download sources from Github:
wget -O 2.1.5.zip https://github.com/msztolcman/hashfile/archive/2.1.5.zip
or
curl -o 2.1.5.zip https://github.com/msztolcman/hashfile/archive/2.1.5.zip
Unpack:
unzip 2.1.5.zip
And install
cd hashfile-2.1.5
python setup.py install
Voila!
