python hashlib code example

Example 1: python hashlib.sha512()

from hashlib import sha512
print(sha512('hello'.encode()).hexdigest())

Example 2: python hash

from hashlib import blake2b
import time
k = str(time.time()).encode('utf-8')
h = blake2b(key=k, digest_size=16)
h.hexdigest()

Example 3: python file hashlib

import hashlib
BLOCKSIZE = 65536
hasher = hashlib.md5()
with open('anotherfile.txt', 'rb') as afile:
    buf = afile.read(BLOCKSIZE)
    while len(buf) > 0:
        hasher.update(buf)
        buf = afile.read(BLOCKSIZE)
print(hasher.hexdigest())
