Detailed explanation-1: -The shift cipher is the simplest mono-alphabetic cipher. it uses modular arithmetic with a modulus of 26.
Detailed explanation-2: -In simple transposition cipher we can simply reorder the plaintext, and then Attack would become KCATTA. We simply reverse the text. The simplest form of substitution cipher is when each character is replaced by exactly one other character (monoalphabetic ciphers).
Detailed explanation-3: -Transposition ciphers reorder units of plaintext (typically characters or groups of characters) according to a regular system to produce a ciphertext which is a permutation of the plaintext.
Detailed explanation-4: -Transposition ciphers rearrange characters or bits of plaintext to produce ciphertext.
