What is file hashing and it is use?
A hash is a function that converts a variable length sequence of bytes to a fixed length sequence.
Hashing files can be advantageous for many reasons. Hashes can be used to check if two files are identical or verify that the contents of a file haven't been corrupted or changed.
You can use hashlib to generate a hash for a file:
import hashlib hasher = hashlib.new('sha256') with open('myfile', 'r') as f: contents = f.read() hasher.update(contents) print hasher.hexdigest()
