  What is Cryptography? Cryptography is protecting the confidentiality and integrity of the information without being vulnerable to attackers or threats. It is an encryption technique when ensures the data is only visible to the sender and recipient and no middle man can steal the data and snoop for information. There are three most common types of cryptographic techniques in general. They are – Symmetric key cryptography   – Here the sender and receiver share a similar key and it can be used for both encryption and decryption. Hash functions  – There is no key used, rather a hash value is used to encrypt text, contents, and passwords. Public key cryptography   – In this two different keys such as a public key for encryption and a private key for decryption is used. Only the private key is kept as secret.
