Write a program that implements an elementary bit stream cipher. An elementary level bit stream cipher is an encryption algorithm that encrypts 1 byte of plain text at a time. This one uses a given 4-bit bit pattern as the key. The size of the encrypted message that we want to be able to send has a maximum length of 200 characters. You must: 1. prompt the user to input the clear text to be encrypted. You must use printf()...
Implement the RC4 stream cipher in C++. User should be able to enter any key that is 5 bytes to 32 bytes long. Be sure to discard the first 3072 bytes of the pseudo random numbers. THE KEY OR THE INPUT TEXT MUST NOT BE HARD CODED IN THE PROGRAM. program should be tested by a plain text You should write TWO PROGRAMS: encryption and decryption. The encryption program should input the plaintext file and output a cipher text in...
C++ Programming Question: This programming assignment is intended to demonstrate your knowledge of the following: ▪ Writing a while loop ▪ Write functions and calling functions Text Processing [50 points] We would like to demonstrate our ability to control strings and use methods. There are times when a program has to search for and replace certain characters in a string with other characters. This program will look for an individual character, called the key character, inside a target string. It...
When using BitLocker (without MBAM): Where can Recovery Keys be accessed? a Recovery Key database in AD b Recovery Key tab in the Computer Object's Properties Without a TPM chip, you will need one of these to use BitLocked systems: a USB Flash Drive b 48-Character Password ID Which of these actions does NOT trigger a BitLocker Recovery: a Moving drive to another PC b Changing docking station c Changing boot device d Changing password
Implement the RC4 stream cipher in C++. User should be able to enter any key that is 5 bytes to 32 bytes long. Be sure to discard the first 3072 bytes of the pseudo random numbers. THE KEY OR THE INPUT TEXT MUST NOT BE CODED IN THE PROGRAM. Test your program with the following plain text: In cryptography, RC4 (Rivest Cipher 4 also known as ARC4 or ARCFOUR meaning Alleged RC4) is a stream cipher. While remarkable for its...

QUESTION 6 What is a hash? O a. A variable key-size stream cipher with byte-oriented operations. The algo Ob. A one-way function that compiles streams of data into a message digest O c. Is used to ensure programs load correctly. Od. Checks the correctness of a program.
Knowledge disclosure is a key way of identifying the organizational culture. Knowledge disclosure techniques such as storytelling allow us to uncover knowledge in the context of its use.IBM views stories as a powerful means of knowledge discovery and knowledge transfer. They are very good for conveying complex messages simply. Storytelling is a unifying and defining component of all organizations, managed and purposeful storytelling provides a powerful mechanism for the disclosure of intellectual or knowledge assets in companies. It can also...
