หลาม
งูหลามมียอดเยี่ยมhashlibห้องสมุดที่ช่วยให้การคำนวณ hashsums sha1หลายรวมถึง นี่เป็นสคริปต์ง่ายๆที่สามารถทำงานได้:
#!/usr/bin/env python3
import sys
import hashlib
import os
from collections import OrderedDict as od
def get_hashsums(file_path):
hash_sums = od()
hash_sums['md5sum'] = hashlib.md5()

hash_sums['sha256sum'] = hashlib.sha256()
hash_sums['sha384sum'] = hashlib.sha384()
hash_sums['sha512sum'] = hashlib.sha512()
with open(file_path, 'rb') as fd:
data_chunk = fd.read(1024)
while data_chunk:
for hashsum in hash_sums.keys():
hash_sums[hashsum].update(data_chunk)
data_chunk = fd.read(1024)
results = od()
for key,value in hash_sums.items():
results[key] = value.hexdigest()
return results
def main():

print(">>> ",path)
for key,value in get_hashsums(path).items():
print(key,value)
if __name__ == '__main__': main()
