pycksum - A Python implementation of the cksum algorithm
The cksum algorithm generates a checksum for a stream of data. While cksum is not cryptographically strong, it can be used to validate the integrity of transferred files.
Pycksum includes a pure Python implementation of cksum as well as an efficient C extension that will automatically be used on platforms that support it.
Installation
Install from PyPi using pip, a package manager for Python:
$ pip install pycksum
Examples
The simplest way to use pycksum is to just give it a string:
import pycksum
ck = pycksum.cksum("Any string")
You can pass in a file or an iterable:
ck = pycksum.cksum( open("filename"))
ck = pycksum.cksum( ["This", "love", "is", "taking", "its", "toll", "on me"])
If you have a lot of data to process, it's more memory-efficient to calculate the cksum incrementally:
c = pycksum.Cksum()
for data in input_fd:
c.add(data)
ck = c.get_cksum()
sz = c.get_size()
