how to create a sha1 hash in python
38,319
You're actually getting 40, which in hex is 0x28
. Decode the hash in hexadecimal to ASCII as follows
>>> import hashlib
>>> hash_object = hashlib.sha1(b'HelWorld')
>>> pbHash = hash_object.hexdigest()
>>> length = len(pbHash.decode("hex"))
>>> print length
20
Or simply use digest
instead of hexdigest
as Dan D suggested.

My objective is to perform "Hashsigning" using smart card in python. there are hashlib's used but there is no specific SHA1 or SHA256 functions in python. My Work:
hash_object = hashlib.sha1(b'HelWorld') pbHash = hash_object.hexdigest()
but the length of the hash object I get is 28 rather i should get 14 or 20 so that i can switch on condition as
switch ( dwHashLen ) { case 0x14: // SHA1 hash call scard transmit case 0x20: // SHA256 hash }
Any help is appreciated. Thank you in advance
