Password Generator
GROUP NAME: Computer Nerds
Create a Random Password Generator using Python
We all
make use of passwords on a daily basis, to keep your account safe and prevent
your password from being hacked we have to make our password is hard enough
that nobody can guess.
We will
learn how to Create a Random Password Generator. We will see the implementation
in Python.
Let’s get started!
What is Password:
A password, sometimes called
a passcode, is a memorized secret, typically a string of characters, usually
used to confirm the identity of a user, In other words is a string of
characters used to verify the identity of a user during the authentication process.
Modules Used:
Random Module:
Random module is used to
perform the random generations. We are making use of random.sample module
here. If you will observe in the output all characters will be unique. random.sample() never
repeats characters. If you don’t want to repeat characters or digits in the
random string, then use random.sample() but it is less secure
because it will reduce the probability of combinations because we are not
allowing repetitive letters and digits.
String Module:
The string module contains a number of
useful constants, classes and a number of functions to process the standard
python string.
1. string.ascii_letters:
Concatenation of the ascii (upper and lowercase) letters
2. string.ascii_lowercase:
All lower case letters
3. string.ascii_uppercase:
All Upper case letters
4. string.digits: The string
‘0123456789’.
5. string.punctuation: String of
ASCII characters which are considered punctuation characters in the C locale.
Now that you are familiar
with password use cases and have acquired basic knowledge of random and string module,
we can move forward to the coding section.
Time to Code!
In order to access the Python
library, we need to import the package in our Python script.
import random
import string
Next, let’s ask the user for
the length of the password.
length = int(input('\nEnter the length of password:
'))
Its time to define the data.
We will make use of string module for the same.
lower = string.ascii_lowercase
upper = string.ascii_uppercase
num = string.digits
symbols = string.punctuation
We have stored lowercase and
uppercase letters along with numbers and symbols. Let’s combine the data and
store the data.
all = lower + upper + num + symbols
Now that we have the data,
let’s make use of random module to finally
generate the password.
temp = random.sample(all,length)
password = "".join(temp)
We are passing in the
combined data along with the length of the password, and joining them at the
end.
Now that you have a clear
understanding of the script, we can even reduce the number of lines of code by
eliminating the storage of data. Let’s have a look.
With
these steps, we have successfully created a random password generator project
using python. That’s it!
Let’s
have look at few sample outputs:
