WebHence the final ciphertext is ‘elsc’ Decryption – Cipher text to plain text. Decryption is the conversion of ciphertext into plain text. It can be done by a simple formula P=(K’)(C) mod26 where P is the plain text, K’ is the inverse key matrix, C is the ciphertext vector or the column matrices.. Input: ciphertext and key Output: plain text. Here the C=’elsc’, which are further ...
