Using python ,

Part 1

Create a program called PasswordManager, that will manage a single password.

The PasswordManager will store the encrypted password (a string).

1. Please initialize a plaintext password

2. Please initialize a ciphertext password that corresponds with the plaintext password as done above)

The PasswordManager has three functions

encrypt: this takes a password (a string) and returns the encrypted form of the password.

validateEncrypt contains the original encrypted password in the parameter

Step 1 - Ask the user to enter their password

Step 2 calls the encrypt function

Step 3 the encrypted password in parameter checked against the password encrypted in step 2

Step 4 - if step 3 is true then the password is valid (this is a print statement)

Step 5 if step 3 is false then the password is not valid (this is a print statement)

verifyPassword: this takes a string (a password) and returns true if it meets the following criteria:

it is at least 8 characters long

it contains at least one letter

it contains at least one digit

it contains at least one of these four characters: , ?, !

• Otherwise it returns false.

If it meets the criteria in verifyPassword and returns true (this is a print statement) if the password meets the requirements otherwise it is false (this is a print statement). Once it is true it then encrypts (calls the Encrypt function) the password and stores it as a variable.

Your program will use the following menu to prompt the user to test the implementation:

A. Change Password

B. Validate Password

C. Quit Enter your choice:

The menu should be processed in a loop, so the user may continue testing the password operations.

The Change Password ( create a new password or change their existing password) option should ask the user to enter a new password ( call the verifyPassword function).

The Validate Password option takes the original encrypted password string. Calls the validateEncrypt function with the original encrypted password in the parameter

par2:

The combination of the secret word and the accepted password make this user unique

Give the secret word a numerical value

Assign a numerical value to each character

Example 1: A = 1, B = 2, C = 3, D = 4, E = 5, , Z = 26

Example 2: A = 2, B = 1, C = 3, D = 5, E = 4, F = 7, where the vowels are even numbers and the constants are odd numbers

Using example 1: If the user enters the secret word bed the encryption is 2 + 5 + 4 which is equal to 11

Define another function called cryptoHash which allows for chained hashing

The hash table size is 4 which has 4 slots ranging from 0 to 3.

Using chained hashing, Hash the secret word to the table

Linked list Class should have 3 fields/variables

Field for the secret word

Field for the password

Field for the link/next

Hash the already encrypted password and the secret word to its slot within the hash table
