C code to Encrypt & Decrypt Message using Substitution Cipher C code to implement RSA Algorithm(Encryption and Decryption) C Program to implement Huffman algorithm Monoalphabetic ciphers are easy to break because they reflect the frequency data of the original alphabet. C++ Server Side Programming Programming It is a mono-alphabetic cipher wherein each letter of the plaintext is substituted by another letter to form the ciphertext. A monoalphabetic cipher uses fixed substitution over the entire message, whereas a polyalphabetic cipher uses a number of substitutions at different positions in the message, where a unit from the plaintext is mapped to one of several possibilities in the ciphertext and vice versa. It is an encryption & Decryption technique which is used for ecrypting and decrypting any message by replacing each character by another character that will be some fixed number of positions down to it. Encryption. until the keyword is used up, whereupon the rest of the ciphertext letters are used in alphabetical order, excluding those already used in the key. That is, the substitution is fixed for each letter of the alphabet. )( .). For each character of alphabet, assign different-abrupt concerned character.
