"WebJan 12, 2024 · (A cipher is an algorithm used for encryption or decryption.) In a substitution cipher, each character of the plain text (plain text is the message which has to be encrypted) is substituted by another character to form the cipher text (cipher text is the encrypted message). The variant used by Caesar was a shift by 3 cipher. " - Cryptography math symbols
