Description
Cryptographic systems play a pivotal role in securing sensitive information in various domains. Permutation ciphers, a fundamental component of classical cryptography, involve the rearrangement of characters in a message to achieve confidentiality. This paper explores the principles and applications of permutation ciphers in cryptographic encryption. The study delves into the historical context, the underlying mechanisms of permutation ciphers, and their relevance in contemporary cryptographic practices. Using permutation on n symbols and Rail Fence Cipher, we construct an algorithm for encrypting and decrypting a message for n = 2, 3
