hashfile 1.0.0

calculate hash or checksum

hashfile

hashfile calculates hashes or checksums in many formats.

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).

Examples

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 md5: 71e875e9d194c18567f48cf9534ed6cf /etc/hosts sha1: e0de09cb8797a4d39f89049d74585e815a3c6ceb /etc/shells

many files, one algorithm

% hashfile -a sha256 /etc/hosts /etc/shells sha256: 48127a192d62fdcaa39f7cebd1ea5f3fe660807c8cd3a92599406d16bddc341a /etc/hosts sha256: edfd1953cce18ab14449b657fcc01ece6a43a7075bab7b451f3186b885c20998 /etc/shells

choose algorithm using symlinks

% ln -s which hashfile ~/bin/sha256 % sha256 /etc/hosts sha256: 48127a192d62fdcaa39f7cebd1ea5f3fe660807c8cd3a92599406d16bddc341a /etc/hosts

Current stable version

1.0.0

Python version

hashfile works only with Python 2.7+.

Usage

Everything is in help :) Just execute:

hashfile --help

Look at result (remember: list of algorithms may differ on your system):

% hashfile --help
usage: hashfile [-h]
                [-a {adler32,crc32,md4,md5,mdc2,ripemd160,sha,sha1,sha224,sha256,sha384,sha512,whirlpool}]
                [--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
  -a {adler32,crc32,md4,md5,mdc2,ripemd160,sha,sha1,sha224,sha256,sha384,sha512,whirlpool}, --algorithm {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.
  --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)

Installation

1. Using PIP

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

2. Using pipsi

   pipsi install hashfile

3. Using sources

Download sources from Github:

wget -O 1.0.0.zip https://github.com/msztolcman/hashfile/archive/1.0.0.zip

or

curl -o 1.0.0.zip https://github.com/msztolcman/hashfile/archive/1.0.0.zip

Unpack:

unzip 1.0.0.zip

And install

cd hashfile-1.0.0
python setup.py install

Voila!
