Day 54 : Calculate a hash of a file

 

import hashlib

BLOCKSIZE = 65536           

# Block read size if file is big enough

fileToOpen = 'E:\\new_python\\new_doc2.txt'

hasher = hashlib.md5()

with open(fileToOpen, 'rb') as afile:

    buf = afile.read(BLOCKSIZE)

    while len(buf) > 0:

        hasher.update(buf)

        buf = afile.read(BLOCKSIZE)

print(hasher.hexdigest())
