Basic of Cryptography (Type of Cryptography)- Part II
Cryptography Types Cryptography categorized based on number of keys used for encryption and decryption; in this article we will discuss below three types Secret Key Cryptography - It is also call symmetric encryption where for both encryption and decryption uses same key. This is mainly used for confidentiality. Public Key Cryptography - It is also called asymmetric encryption ; this algorithm uses two key's one for encryption and one for decryption. mainly used for authentication. Hash Function - It uses to convert to text in such way that the input cannot be recoverable by using mathematical function.
