Cryptography is the practice of secure communication in the presence of third parties. It is a technique of converting data into a secret code so that only the intended recipients can read it. Cryptography has been used for thousands of years to protect information, starting with ancient civilizations who used simple ciphers to encode messages. In modern cryptography, complex algorithms are used to create codes and keys that are nearly impossible for unauthorized users to break. These algorithms are based on mathematical principles and are designed to ensure the confidentiality, integrity, and authenticity of data. There are two main types of cryptography: symmetric and asymmetric. In symmetric cryptography, the same secret key is used to encrypt and decrypt the message. The sender and receiver of the message must have the same key. This type of cryptography is faster than asymmetric cryptography and is commonly used to encrypt large amounts of data. In asymmetric cryptography, two dif
