Cryptography

Cryptography, by definition means the way of converting human readable data to encrypted data. Data is being encrypted by the original user(i.e. by the sender) and being decrypted at other end (i.e. by the receiver).
The encrypted data is then decrypted by the receiver by using certain decryption algorithms. There are various hashing algorithms that are used to encrypt the data into cipher text.
Cryptography algos are categorized into three parts:-
1. Hash Functions
2. Secret Key Cryptography
3. Public Key Cryptography
