hash v2 and v3 help

[Normalitie]

You're right.

I think the problem is that he's converting to the bytes the "key" string instead of "c41d9eac" :)

Thanks. This was indeed the problem.
Original:

import hashlib
key = 'c41d9eac'
print(hmac.new(b'key', b'this is the life', hashlib.sha1).hexdigest())

Solution:

import hashlib
key = b'c41d9eac'
raw = 'this is the life'
print(hmac.new(key, raw.encode(), hashlib.sha1).hexdigest())

Thanks again for your help.
