Develop a software authentication module for your software (any type of and in anyprogramming language). Use a hash algorithm to obtain a hash code of user passwords.I) Store only hash code instead of raw passwords (identification). II) When a user requests an authentication, for an attempt to verification, create a hashcode of password and compare the stored one. III) If a match occurs, then authenticate the user. If authentication fails, inform the userproperly.
- Explain the advantages of allowing the user program to access the virtual addresses rather than the real physical addresses - Explain how dynamic loading differs from dynamic linking.

def delete_account(user_accounts, log_in, bank, username, password): ''' Completely deletes the user from the online banking system. If the user exists in the user_accounts dictionary and the password is correct, and the user is logged in (the username is associated with the value True in the log_in dictionary): - Deletes the user from the user_accounts dictionary, the log_in dictionary, and the bank dictionary. - Returns True. Otherwise: - Returns False. For example: - Calling delete_account(user_accounts, log_in, bank, "BrandonK", "123abcABC") will return False - Calling delete_account(user_accounts, log_in, bank, "Brandon", "123abcABDC") will return False - If you first log "Brandon" in, calling delete_account(user_accounts, log_in, bank, "Brandon", "brandon123ABC") will return True
Write in C sharp programming Write a program that encodes and decodes a string using given encryption key (cipher). The key consists of a sequence of characters. The encoding/decoding is done by performing XOR (exclusive or) operation over the first letter of the string with the first of the key, the second – with the second, etc. When the last key character is reached, the next is the first.

Using C++ do the following - Create a structure for student (ID, Name, address all strings) - Create hash table class with the required methods for students based on their address. Hash table contents should be the index of the element in the original array. - In Main function - Put three student objects in an Array. - Create Hash table object of size = 7 - Insert the indexes of those objects into a hash table object from the hash table class.
Nodes contain two parts, the first part stores the actual data and the second part has a pointer that points to the next node. * True O False

9:05 Part 2: Encryption Details: description Objective: Develop a program that encrypts a plaintext file by XORing 128-bit blocks of the file with a key repeatedly until the entire file is encrypted. • The plaintext file will be a book from Project Gutenberg. Note: Done • The encryption method should use the XOR operation on the file, 128 bits at a time, with the key. • Each 128-bit block is XORed with the same key. • The program should work from the command line and accept three parameters: o The name of the key file Usage: o The name of the plaintext file o The desired name of the resulting ciphertext file This encryption method is not supposed to be secure.
