Detailed explanation-1: -Ciphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can’t be read until it has been converted into plaintext (decrypted) with a key. The decryption cipher is an algorithm that transforms the ciphertext back into plaintext.
Detailed explanation-2: -For example, in the Caesar Cipher we saw how each letter in the alphabet was mapped to a different letter. For example, A→D, B→E, and C→F, when we’re using a shift of four. This kind of cipher is known as a shift cipher.
Detailed explanation-3: -Caesar Cipher. In Caesar cipher, the set of plain text characters is replaced by any other character, symbols, or numbers. Monoalphabetic Cipher. Homophonic Substitution Cipher. Polygram Substitution Cipher. Polyalphabetic Substitution Cipher. Playfair Cipher. Hill Cipher.
