how to automate the htpasswd password entry in python scripts

Question

This is my python function that creates the htpasswd file and adds the username and password in it .

def __adduser(self, passfile, username):

        command=["htpasswd", "-c", passfile, username]
        execute=subprocess.Popen(command, stdout=subprocess.PIPE)
        result=execute.communicate()
        if execute.returncode==0:
            return True
        else:
            #will return the Exceptions instead
            return False

It is working great but the only improvement I want is, how to automate the password entry it ask for after running the scripts that should be set from some variable value

I'd rather look at an existing Python implementation/wrapper than trying to go through a CLI subprocess here… https://pypi.python.org/pypi/htpasswd — deceze, Aug 23 '17 at 07:46

the problem I got into using the htpasswd is ,the new username get appended if the file already exists. I want just a single file with single entry. that htpasswd cant fulfill — Tara Prasad Gurung, Aug 23 '17 at 07:50
You basically just want to delete the file, then create a new one. That's what the `-c` flag does. You can do that perfectly fine in Python, even if the PyPi htpasswd library doesn't offer a specific option for that. — deceze, Aug 23 '17 at 08:13
that is the reason i am using -c there and didn't use the module — Tara Prasad Gurung, Aug 23 '17 at 09:13

htpasswd has an -i option:

Read the password from stdin without verification (for script usage).

So:

def __adduser(self, passfile, username, password):
    command = ["htpasswd", "-i", "-c", passfile, username]
    execute = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
    execute.communicate(input=password)
    return execute.returncode == 0

Use bcrypt python module to create a password

import bcrypt

def encrypt_password(username, password):
    bcrypted = bcrypt.hashpw(password.encode("utf-8"), bcrypt.gensalt(rounds=12)).decode("utf-8")
    return f"{username}:{bcrypted}"

print(encrypt_password("client", "ClientO98"))
