- A shorter message makes it harder to attack the cipher since it is easier to read.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…While attempting to decipher a short message, assaults on a cipher provide a greater challenge since they are more difficult to break.
- 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.Data Encryption Standard Perform a Data Encryption Standard encryption on the plaintext (PL) by using key (K). The PL is your first 8 characters of your name and K is the last 8 digits of your student ID. For example: Name: Siti Fajar Plain text (PL): SITIFAJA Student ID: 201908040016 Key (K): 08040016 Show detail step by step involved.Attacks on a cypher are more difficult for a short message since they are more difficult to break.
- Master of Fine Arts degrees are something I've always been interested in but never took the time to research. If someone other than the person for whom it was intended is able to decrypt a password, then the value of the password will drop.The act of encrypting data is referred to as the "salt" procedure in the field of cryptography. You are need to explain how it is used to make passwords 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…
