FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Breaking a code (that is, reading encrypted messages without having the secret information) is called cryptanalysis.

Detailed explanation-2: -What is the difference is between “cracking” a code and “decrypting” a message? Cracking a code is when you attempt to decode a secret message without knowing all the specifics of the cipher and decryption is when you already know the key and are trying to reverse the process of encryption.

Detailed explanation-3: -Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography.

Detailed explanation-4: -To decode a message, you do the process in reverse. Look at the first letter in the coded message. Find it in the bottom row of your code sheet, then find the letter it corresponds to in the top row of your code sheet and write it above the encoded letter.

Detailed explanation-5: -A cryptanalyst’s duties may include developing algorithms, ciphers and security systems to encrypt sensitive information and data as well as analyzing and decrypting different types of hidden information, including encrypted data, cipher texts and telecommunications protocols, in cryptographic security systems.
