Python.PasswordVault

PasswordVault is a proof of concept password vault in python using One Time Pad encryption. It uses the master password to encrypt passwords that the user enters. Bear in mind that this is a proof of concept program and therefore should not be used as you password manager. If you are looking for one of them, there are plenty to choose from on the web...

How to use the program

PasswordVault has been written in Python 3.6 but should work in all versions of Python 3 (however, it will not work in (Python 2). The program runs in the command window (or IDLE) - it is therefore text based. Enter your master password (when you first run the program copy the one it gives you - for subsequent times, ignore it). Then enter single characters to add a password, remove a password, show passwords or quit the program

• Add password - A (Default option)
• Remove password - r
• Show passwords - s
• Quit - q

General Code Overview

Import sys to exit the program, random to generate a master key and io to read and write to files

Global list containing encrypted passwords and key

masterPassword for the example text file containing passwords "hello" and "why" - I advise you choose better passwords for sites! masterPassword = ,B3U*]Y)gO'aC(B|gGx1

start() Opens the password file and writes each password to the passwords list then prompts the user to enter their master password

choice() Prompts the user to choose what they want to do next (default is Add Password) - "Add Password, Remove Password or Show Passwords or Quit? (A/r/s/q)"

myquit() Writes the passwords to the password file and exits the program (save and quit)

remove() Shows the passwords, Prompts the user to select the index that they wish to remove and then removes that password, and finally shows the updated passwords

encrypt() Takes a password, encrypts it using the master password and writes it to the passwords list

decrypt() Runs decrypt_part (the bit that actually decrypts and then choice()) - not particularly good but saved me rewriting code

decrypt_part() Takes all encrypted passwords from the list, decrypts and prints them (password list stays encrypted)

genMasterPassword() Generates the master password (20 characters long)

start() Starts the program
