Explanation

External Dependencies

import streamlit as st
import random

AI-generated code. Review and use carefully. More info on FAQ.

• Streamlit is imported to create the web interface.

• Random is imported to generate random characters for the password.

Initializations

lowercase = list(range(97, 123))
uppercase = list(range(65, 91))
digits = list(range(48, 58))
special = list(range(33, 48)) + list(range(58,65)) + list(range(91,97)) + list(range(123,127))

• These lists represent ASCII values for different character sets:

  • lowercase: ASCII values for ‘a’ to ‘z’.

  • uppercase: ASCII values for ‘A’ to ‘Z’.

  • digits: ASCII values for ‘0’ to ‘9’.

  • special: ASCII values for special characters like !, @, #, etc.

Streamlit App

st.header("Password Maker")
st.write("This application will generate a password based on the desired criteria.")

• Sets up the header and description for the app.

User Inputs

size = st.number_input(label="Enter the length of the password. (Minimum 8)", min_value=8, step=1, key="pwd_size")
has_upper = st.toggle(label="Contain Uppercase letters?", key="pwd_upper")
has_digit = st.toggle(label="Contain numbers?", key="pwd_digit")
has_special = st.toggle(label="Contain Special Characters?", key="pwd_special")
make_pwd = st.button("Generate Password")

• size: Input for the length of the password (minimum 8 characters).

• has_upper: Toggle for including uppercase letters.

• has_digit: Toggle for including digits.

• has_special: Toggle for including special characters.

• make_pwd: Button to generate the password.

Password Generation

if make_pwd and size >= 8:
    if has_upper:
        options.extend(uppercase)
    if has_digit:
        options.extend(digits)
    if has_special:
        options.extend(special)
    
    while len(password) <= size:
        password += chr(random.choice(options))
    
    st.write(f"The generated password is: {password}")
    options = lowercase.copy()

• Condition: Checks if the button is clicked and the size is at least 8.

• Options Update: Adds selected character sets to the options list.

• Password Loop: Generates a password by randomly selecting characters from the options list until it reaches the desired length.

• Display: Shows the generated password.

• Reset: Resets the options list for reuse.
