Python library for calculating CRC16

CRC is a way of detecting accidental changes in data storage or transmission. There are many variants of CRC and CRC16, in particular. This library calculates only CRC16 (16-bit codes) and the only supported variant at the moment is CRC-CCITT (XModem).

If you want to know more about CRC, is a good place to start.

If you want other variants of CRC16 supported, please make a request at

Source codes are hosted at If you want to contribute to this library, create a fork, make you changes and then create a pull request. Any help is appreciated.

Installation

On Windows you can use precompiled binaries which can be found at

On Linux and other operation systems you should compile the library from the source codes. To do this on Linux use following steps:

download source tarball, e.g. crc16-0.1.1.tar.gz, from
extract it with command:
```
tar -xzf crc16-0.1.1.tar.gz
```
compile and install the library:
```
cd crc16-0.1.1
python setup.py build
sudo python setup.py install
```
you will need the administrative privileges to execute the last command.

After installation you can run unit tests to make sure that the library works fine. Execute:

python -m crc16.test

Usage

In Python 3:

import crc16
print(crc16.crc16xmodem(b'123456789'))

In Python 2 you should use strings instead of binary data:

import crc16
print(crc16.crc16xmodem('123456789'))

You can also calculate CRC gradually:

import crc16
crc = crc16.crc16xmodem(b'1234')
crc = crc16.crc16xmodem(b'56789', crc)
print(crc)

Other projects

There are a number of projects and libraries for CRC calculation. See for example:

binascii.crc32 in the standart Python library
pycrc ()
crcmod ()
