Cryptography . . . C ryptography the use of codes or ciphers to protect the secrecy of a message or data or any short of communication between two parties or a group of people.The history of cryptography began way back in the medieval period where messages were carved in caves in a way that it was readable to only those who had access to the codes or who knew what those symbols mean. Cryptography has traveled a long journey from Classic Cryptography using pen and paper to solving complex mechanical encryption such as the Enigma Rotor Machine . How Cryptography works? T he modern cryptography or encryption over data is achieved by using algorithms ( cryptographic algorithms are designed to convert letters or numbers or words or any kind of data into an encrypted/decrypted form using a specific key ) . In this algorithm method ,the sender has an algorithm the sender feeds some data to the encryption algorithm as an input and then the sender sets...
