Password Manager

View project here password is pw123.
This is a demo project please do not store any real passwords as passwords are returned as plain text to the users when viewing passwords

For this project I have built a terminal password manager in python, the program allows the user to input & save new passwords along with view passwords based on the website name, username/email, or password name.

All the passwords are encrypted and stored on a PostgreSQL database on Heroku, when the user retrieves the passwords they are decrypted and displayed to the user

Responsiveness was checked using Am I responsive, although I’ve used the template provided mobile input does not seem to work

Deployment

The project and database are deployed on Heroku, under the same project using the hobby plan

Python Project

• Once project is ready enter pip3 freeze > requirments.txt into the command line to build requirements file

1. Head to Heroku
2. New > Create new app
3. Add a unique name and choose the region
   • Europe was used for this project
4. Create app
5. Set the build packs as
   • Python
   • Node.js
6. Add Config Vars
   • PORT 8000 needs to be included
7. Link the GitHub repository
8. Deploy the project

PostgreSQL database

1. In the Heroku project head to Resources
2. Search for PostgreSQL in add-ons
3. Select plan
   • Hobby plan was used for this
4. Get database credentials by clicking on the database name
5. Set up preferred database tool with the info

Features

Current features

Currently, the password manager offers its users the ability to:

• Login via authentication
• Create a new password entry
  • Username
  • Password
  • Website name
  • Unique password name
• Generate a random password between 8 and 25 characters long
• Save the password to the database
• Search the database for a password by
  • Website name
  • Password name
  • Search for all passwords

Future features

In future build if this password manager I would like to offer the abilities:

• Update the master password for authentication
• Edit passwords:
  • Username
  • Password
  • Website name
  • Password name

Validation Testing

The code base was checked using PEP8 online check, there are several E501 errors showing that lines are too long,

When reviewing the code in PyCharm IDE, the errors showing up are that some variable may be referenced before assignment, there is also a typo error shown for the opening string when signing in but the word ‘Kittridge’ is spelt right.

Bugs:

Solved bugs:

• One of the main bugs I was running into with the project was I encrypted the password using base64 but was decrypting it in base16 which caused an illegal key error: None-base16 digit found

This was resolved by changing the decode function to use base64 format

• Another bug I ran into was when I attempted to convert the original key of 2 separate sales into bytes there was an encoding error, this was caused by not adding utf-8 to the conversion

• The main bug I encountered was with the decrypt function, where for some passwords the decryption method was looking for additional padding being added to the encrypted password, when being passing in via a variable. When I was passing the string in directly the password was bing decrypted as expected.

These 2 bugs were resolved by rewriting how the passwords were encrypted and decrypted. I used a python package called cryptography which handled encoding and decoding the passwords by using a randomly generated key

Unsolved bugs:

There are no unsolved bugs
