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. WebFive-bit binary codes. Several different five-bit codes were used for early punched tape systems. Five bits per character only allows for 32 different characters, so many of the five-bit codes used two sets of characters per value referred to as FIGS (figures) and LTRS (letters), and reserved two characters to switch between these sets.

WebApr 10, 2024 · Hiding some data is known as encryption. When plain text is encrypted it becomes unreadable and is known as ciphertext.
