Detailed explanation-1: -Transposition Cipher is a cryptographic algorithm where the order of alphabets in the plaintext is rearranged to form a cipher text. In this process, the actual plain text alphabets are not included.
Detailed explanation-2: -Substitution Ciphers. Substitution ciphers encrypt the plaintext by swapping each letter or symbol in the plaintext by a different symbol as directed by the key. Perhaps the simplest substitution cipher is the Caesar cipher, named after the man who used it.
Detailed explanation-3: -In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters (transposition) without changing the characters themselves.
Detailed explanation-4: -A transposition cipher, also called columns permutation, is a technique to change the order of the letters in a text by placing it in a grid.
