WebMay 28, 2024 · An encrypted plain-text is a cipher-text. A Plain-text - like its name says - is an unencrypted text. The Caesar cipher is a simple encryption in which every plain-text letter of a given string is shifted by a given key. Like schroeder said, your question looks awfully specific and it seems to be a homework question. WebApr 6, 2024 · Thus to cipher a given text we need an integer value, known as a shift which indicates the number of positions each letter of the text has been moved down. The encryption can be represented using modular arithmetic by first transforming the letters into numbers, according to the scheme, A = 0, B = 1,…, Z = 25.

CBC is the most popular mode, which requires the IV and requires plaintext be padded up to the block size. So, let's say you want to encrypt 4 bytes with AES CBC. You would need 16 bytes for the IV, and those 4 bytes need to be padded to 16 bytes, for a total of 32 bytes.
