Convert String To Base 64 From Sha1 Hash In Python

I have a small C# function that I want to use in Python. However Im not sure how to use hashlib to accomplish the same result. The function receives a string an returns the base64

Solution 1:

The difference in the output stems from the encoding you are using:

• in your C# code, UnicodeEncoding encodes the input string (word) as UTF-16 little endian; and
• in your Python code, you're not even handling Unicode strings (they must be encoded as some bytes)

So, just encode the word as UTF-16 little endian before hashing:

import hashlib
import base64

defconvert_string_to_hash(word):
    digest = hashlib.sha1(word.encode('utf-16-le')).digest()
    return base64.b64encode(digest)

Also, your Python function can be somewhat shortened.

Solution 2:

The following worked for me for storing in LDAP. Hex matched, but it was that base64 encode that brought it over the line - python3.

    newSaUserPassword = "{SHA256}" + \
                        base64.b64encode(hashlib.sha256(options.newSaUserPassword.encode("utf-8")).digest())
