Application example

from password import PasswordManager

1. First of all we instantiate the class:

pm = PasswordManager() # it will use the default atributtes

2. We create a password:

mypassword = pm.CreatePassword()

print('My password is:', mypassword) # My password is: p7.!FDf1

3. We check that the password has been internally stored

print(pm.IsExistingPassword(mypassword)) # This password has been used

print(pm.IsExistingPassword('sdfdfa')) # This password has never been used

4. We instantiate the second class

cp = CustomisingPassword() # it will use the default atributtes

5. We create a customised password containing a desired word

new_password = cp.CreateCustomisedPassword('Elene')

print('My new customised password is: ', new_password) # My new customised password is: Elene12=

6. Check it the customised password is secure

print(cp.IsMyPasswordSecure(new_password)) # Your password is secure

7. Now that we have created a customised password and it is secure we save it as current password

print(cp.ChangeCurrentPassword(new_password)) # Your password has been changed successfully
