Code Assignment: Brute Force Attack Using the following method to decrypt a single letter with a given key, write a program which prompts for and receives a ciphertext string, then displays all 25 possible decryptions. Shift cipher decryption. Call for each letter of ciphertext eparan c -the ciphertext letter (upper case eparan k - the key, the number of letters to shift by ereturn p - the plaintext letter (lower case) publie static char decrypt (char c, int k) if(p e) p26; return (char)(p ') Use your program on the tollowing message.
