Cryptography Basics
C ryptography is an art of hiding important or valuable information in a form which general users can’t understand. It’s a process of securing data and information. There are three types of cryptography. Symmetric cryptography : When we will solve CTF problems , we will get this types of cryptography a large numbers. Symmetric cryptography where always has a common key for encryption and decryption. We have to use the common key to decrypt the encrypted message. Common types of symmetric cryptography which we face in CTF challenges are: Caesar Cipher Rot13 Vigenere Cipher Morse Code Bacon Cipher Alphabetical Substitution The tools we use for decryption are: CyberChef ( website ) Caesar cipher( website ) vigenere solver ( website ) 2. Hash Function Cryptography : There is no common key value like as symmetric cryptography. But in this cryptography, there has the...
