- Short messages make cypher attacks more challenging since they are harder to crack.Attacks on a cypher are more difficult for a short message since they are more difficult to break.Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading. Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern. For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example: Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext = "WKH FDW LV YLVLEOH DW PLGQLIJKW" The keys to decrypt this message are the shift number…

- In cryptography, the process of encrypting data is called the "salt" operation. You'll need to describe how it's put to use to make passcodes harder to crack.Cryptography is the study of protecting information. A cipher is a pair of algorithms ―the first algorithm encrypts a message and the second algorithm decrypts the message. In most cases, a unique key is also required to encode or decode plaintext. The Caesar cipher is one of the simplest and most widely known ciphers. It is named after Julius Caesar who allegedly used it to protect important military directives. Every letter in the plaintext is replaced by a letter N positions down the alphabet. For example, if N = 3, then a => d and b => e. While the idea is remarkably simple, it appeared to work in Ancient Rome. Most people there couldn't read, and those who could simply assumed it was a foreign language. Write a program that implements the Caesar cipher. You program will get from standard input the key N, followed by a line of plaintext. . . The key N should be any integer between 0 and 26 inclusive. If this isn't the case, print an error message and quit. Any numbers or…Create an attack tree for stealing a car. Create an attack tree for getting into a gym without paying.

- Respond to the following in a minimum of 175 words: Discuss a cryptography attack scenario. Choose an attack and explain how it works. Be sure to choose one that hasn’t been mentioned by another classmate. What countermeasures would you apply? How do the countermeasures you would use compare to those your classmates recommended for the attacks they chose? What do those similarities or differences tell you about fighting these types of attacks?The word "salt" is used in cryptography to describe the process of encrypting data. You need to explain how it is used to make passwords more difficult to break.In cryptography, the Caesar cipher is a type of scroll cipher and is one of the simplest and best-known ciphers.
