Write a java program to encrypt and decrypt a message. The user should be able to choose between a Caesar cipher or a Vigenere cipher for their message. Use JOptionPane for user input.
Use the python erypto library to demonstrate how to encrypt and decrypt a message using AES n ECB mode. The python interrupter is installed by default with Kali Linux Take screenshots of command walkthrough and explain your steps Note: You will need to create a separate object for encryption and decryption similar to the example illustrate in the course slides You can also use pydoc command to view the documentation for the library. For example if you type: pydoc Crypto.cCipher.AEs...
The next two problems use a tabular transposition cipher with keyword "VENUS". 23. Encrypt the message "MATHISSOMUCHFUN" 24. Decrypt the code "AOMRVOMEASRKEDEAHGUB".
Using RSA cipher, public key e=3, private key d=7 Encrypt the following message “Hello there” Decrypt the previous message
Write helpful comments for the following code: use Vigenere cipher tech to encrypt and decrypt message The code: #include<stdio.h> #include <stdlib.h> char arr[26][26]; char message[22], key[22], emessage[22], retMessage[22]; int findRow(char); int findColumn(char); int findDecRow(char, int); int main() { int i = 0, j, k, r, c; k = 96; for (i = 0; i<26; i++) { k++; for (j = 0; j<26; j++) { arr[i][j] = k++; if (k == 123) k = 97; } } printf("\nEnter message\n"); fgets(message, 22,...
C Programming - RSA encryption Hi there, I'm struggling with writing a C program to encrypt and decrypt a string using the RSA algorithm (C90 language only). It can contain ONLY the following libraries: stdio, stdlib, math and string. I want to use the following function prototypes to try and implement things: /*Check whether a given number is prime or not*/ int checkPrime(int n) /*to find gcd*/ int gcd(int a, int h) void Encrypt(); void Decrypt(); int getPublicKeys(); int getPrivateKeys();...
1. Encrypt the message howareyou using the affine cipher using the key (7,3). (a) What is the resulting ciphertext? (b) What is the decryption function you can use to decipher each ciphertext character? (c) Use your decryption function to decrypt the message to confirm you get the ciphertext back. 2. Use the ADFGX cipher using the grid below and the keyword "place" to encrypt the plaintext "brandenburggate". FREE GX (a) (b) What is the resulting ciphertext? How does the ADFGC...
C Programming - RSA Encryption I've tried to write a program that can encrypt and decrypt strings using RSA and want to be able to integrate it into a header file which contains codes for compression, linked list etc.. However, the use of global variables and fixed size of encryption is making it hard to do so Can someone please help me modify the following the code? I want to be able to just pass it in a string to...
