Explanation of Solution
Caesar cipher for Greek language:
Note: Refer the “A complete java class for performing the Caesar cipher” in the text box.
Changes in complete java class for performing the Caesar cipher:
A complete java class for performing the Caesar cipher explains the encryption and decryption of English language using Caesar cipher.
Now,
Let us consider the program explains the encryption and decryption of Greek language using Caesar cipher.
- Change the new alphabets and its size. That is, the new alphabets are Greek alphabets “A, B, Г, Δ, E, Z, H, Θ, I, K, Ʌ, M, N, Ξ, O, П, P, Σ, T, ϒ, Φ, X, Ψ, Ω” and its size of array is “24”...

Implement a SMS spam detection program in python using the Naive Baiyes algorithm. The program should be coded completely from scratch that is without the help of any libraries or imported libraries or packages. Note that you should use a dataset in this task and we shall be able to test it by entering a message too.
Implement the first round of AES ( Advanced Encryption Standard ) in python.
Given a message with 128 bits, two subkeys subkey0 and subkey1, your program should be able to perform one AddKey before Round 1 and the corresponding operations (SubBytes, ShiftRows, Mix-Columns, and AddKey) in Round 1, and output the result of the encryption after Round 1.
C programming
Implement an encoder. When completed, your program should be able to accept a short sentence from the user and display an encrypted version of it. For simplicity, let us assume one case of letters throughout, say CAPITALS. We can use a substitution method to scramble a sentence and then use the reverse of this process to recover it. If we take two rows of the alphabet and shift the bottom row along a specified amount (our key), we can then read the letters in our sentence from the top row and use the substituted letter from the bottom row to form the encrypted sentence.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
X Y Z A B C D E F G H I J K L M N O P Q R S T U V W
In the example above, the key is 3, hence the second row is shifted by three characters along. Take, for instance, the sentence “HELLO”. Each letter of your message should be replaced by the letter in the alphabet that comes three letters before. For “HELLO” that would be: EBIIL

A Caesar cipher performs a shift of all of the characters in a string (based on their ASCII values, see Table 2.1), e.g. h e l l o → m j q q t The example shows a shift with a distance of 5 characters, i.e. h(ASCII:104) → m(ASCII:109) Write a C/C++ program that asks the user to input a line of plaintext and the distance value and outputs an encrypted text using a Caesar cipher, with the ASCII values range from 0 through 127. Use underscores (ASCII: 95) to represent space characters. Underscore characters should not be encrypted, and any character that is encrypted may not become an underscore. In this case, the character should be changed to the next character in the ASCII table. The program should work for any printable characters. NB: No strings (datatype) or library functions may be used. See Figure 2.1 for example output.arrow_forward
- Write a Java program to encrypt and decrypt a phrase using two similar approaches, each insecure by modern standards. The first approach is called the Caesar Cipher, and is a simple "substitution cipher" where characters in a message are replaced by a substitute character. The second approach, due to Giovan Battista Bellaso (b 1505, d 1581), uses a key word, where each character in the word specifies the offset for the corresponding character in the message, with the key word wrapping around as needed.arrow_forwardIn c++ pleasearrow_forwardA Caesar cipher is a simple substitution cipher based on the idea of shifting each letter of the plaintext message a fixed number (called the key) of positions in the alphabet. For example, if the key value is 2, the word "Sourpuss" would be encoded as "Uqwtrwuu." The original message can be recovered by “reencoding" it using the negative of the key. Write a program that can encode and decode Caesar ciphers. The in- put to the program will be a string of plaintext and the value of the key. The output will be an encoded message where each character in the orig- inal message is replaced by shifting it key characters in the Unicode char- acter set. For example, if ch is a character in the string and key is the amount to shift, then the character that replaces ch can be calculated as: chr (ord (ch) + key). 62arrow_forward

- Experiment 1: IMPLEMENTATION OF CAESAR CIPHER Objective: To implement the simple substitution technique named Caesar cipher using C+ language. Theory: To enerypt a message with a Caesar cipher, each letter in the message is changed using a simple rule: shift by three. Each letter of the message is shifted a fixed distance (3 for example) down the alphabet, A becomes D, B becomes E, and so on. For the last letters, we can think of alphabet as a circle and "wrap around", W becomes Z. X becomes A, Y becomes B, and Z becomes C. To change a message back, cach letter is replaced by the one three before it.
