Substitution in cryptography

WebThe substitution technique involves replacing letters with other letters and symbols. In simple terms, the plaintext characters are substituted, and additional substitute letters, numerals, and symbols are implemented in their place. The Caesar cipher employs the substitution technique. WebThe simplest of all substitution ciphers are those in which the cipher alphabet is merely a cyclical shift of the plaintext alphabet. Of these, the best-known is the Caesar cipher, used …
