在Python中模拟PHP的sha1原始输出

Question

I am using Django to make an e-shop. I am trying to add online payment with http://liqpay.com/. They have examples in PHP: https://liqpay.com/?do=pages&p=cnb12.

In the example they use PHP's shal($data, 1) flag 1 (then the sha1 digest is instead returned in raw binary format with a length of 20).

But the Python function hashlib.sha1(), does not have this flag.

Is there some analog in Python?

Answer 1

Python hashlib objects can provide you with either the raw bytes or a hex digest, depending on the method used. Calling .digest() gives you raw bytes:

>>> import hashlib
>>> data = 'foobar'
>>> hashlib.sha1(data).digest()
'\x88C\xd7\xf9$\x16!\x1d\xe9\xeb\xb9c\xffL\xe2\x81%\x93(x'
>>> len(hashlib.sha1(data).digest())
20

If you want to get the hex digest, use the .hexdigest() method instead:

>>> hashlib.sha1(data).hexdigest()
'8843d7f92416211de9ebb963ff4ce28125932878'
