- q5- The Atbash cipher is a type of monoalphabetic cipher formed by taking the alphabet and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example: A becomes Z and Z becomes A, B becomes Y and Y becomes B, and so on. Numeric digits and special symbols will remain the same. What does XHV2HRZ mean?In cryptography, the Caesar cipher is a type of scroll cipher and is one of the simplest and best-known ciphers. When encrypting a message in the Caesar cipher, each letter is usually replaced by the letter three letters in the alphabet. Let the alphabetic scrollback look like this: aw w ww ww m ww w ww w vwwwwwww www ww wwm w w wwwm www ww defg hijkI mnop 9rstuvwxy z abc a bcd efghilj kI P9rstu v w xy z m Keep the encryption in the Python dictionary structure. www ww Write a Python program that takes the three-letter message as input and prints the encrypted message.

- 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…Exercise - 1 Exercise – 1: P and Q are two prime numbers. P=7, and Q=17. Take public key E=5. If plain text value is 6, then what will be cipher text value according to RSA algorithm? Again calculate plain text value from cipher text.Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data.

Use 5 characters per row.Exercise - 5 Exercise - 5: P and Q are two prime numbers. P-13, and Q=17. Take public key E=19. If original message is 12, then what will be cipher text value & private key value according to RSA algorithm? Again calculate plain text value from cipher text.
- True or False 9. An example of a lightweight cryptographic block cipher is the Scalable Encryption Algorithm.Q1: Secret Messages Implement a Caesar cipher to encrypt messages.Question 1 Study the scenario and complete the question(s) that follow: Ceasar Cipher The Caesar Cipher technique is one of the earliest and simplest method of encryption technique. It's simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example with a shift of 1, A would be replaced by B, B would become C, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials. 1.1 Write a Ceasar cipher algorithm in such a way that a character D is changed to N. Derive the encryption of the other characters accordingly. 1.2 Based on your algorithm, what will be the encrypted code of the message “my mother is not home". End of Question 1
