WebModular Math and the Shift Cipher. The Caesar Cipher is a type of shift cipher. Shift Ciphers work by using the modulo operator to encrypt and decrypt messages. The Shift Cipher has a key K, which is an integer from 0 to 25. We will only share this key with people that we want to see our message. WebApr 11, 2024 · Example: encrypted Level 1 data that is copied from a desktop to a USB drive (or external hard drive) will not be encrypted – unless the storage media is also managed as an encrypted device. The most reliable way to protect Level 1 data is to avoid retention, processing or handling of such data.
