NWS620S Tutorial 1: Symmetric Encryption - DES Encryption is the translation of data into a secret code so that only authorised entities can read it. Encrypting data is considered a very effective way of achieving data security. To access encrypted data, you must have access to a secret key that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text. There are two types of encryption: • Symmetric encryption • Asymmetric...

USE C++!!!! Encryption and Decryption are two cryptographic techniques. Encryption is used to transform text to meaningless characters, and decryption is used to transform meaningless characters into meaningful text. The algorithm that does the encryption is called a cipher. A simple encryption algorithm is Caesar cipher, which works as follows: replace each clear text letter by a letter chosen to be n places later in the alphabet. The number of places, n, is called the cipher key. For example, if...

In this project you implement a program such that it simulates the process of repeated attempts to hit a target with a projectile. The goal is to shoot the projectile within a 1 foot distance from the target, since such a short miss is accepted as a hit. Your program is responsible for the following tasks. Compute the trajectory data of a projectile (such as the time, the maximum height and the distance as described by the formulas above) for...
