I have been given a file with user and passwords in the format: $id$salt$hashed.
Where ID stands for the type of encryption and id=1 stands for FreeBSD-style MD5.
There is an example in which I know the password= "alice"
jsmith: $1$kDHTx$WKRXXT1P7UtjvU7CQ9eWs/:10063:0:99999:7:::
So I have done this in Python to check
import hashlib
passw='alice'
salt='kDHTx'
hashed= hashlib.md5(salt+passw).hexdigest()
print('What i get is: '+hashed)
print('What i should: '+'WKRXXT1P7UtjvU7CQ9eWs')
But I dont even get the format correctly:
What i get is: ba359e6dd36371c4dc5c187aac11e0d8
What i should: WKRXXT1P7UtjvU7CQ9eWs
What am I doing wrong? Or even understanding wrong from the begining?

You need to use the crypt
library instead of hashlib
.
>>> import crypt
>>> crypt.crypt('alice', crypt.METHOD_MD5)
$1$tlyP8ine$I9F3AiUCIgOjREqbx6WUg0
The salt is generated by the function when you pass in crypt.METHOD_MD5
.
To re-create an existing hash, you can pass it in as the second argument:
>>> crypt.crypt('alice', '$1$kDHTx$WKRXXT1P7UtjvU7CQ9eWs/')
$1$kDHTx$WKRXXT1P7UtjvU7CQ9eWs/
