Public Key Cryptography What is Public Key Cryptography ? It is a cryptographic technique that involves two distinct key for encryption and decryption is known as public key cryptography. It is also known as asymmetric key cryptography. Among two key, one key is called public key and the another key is called private key. Here, public key is publically available and private key is kept private to particular user. Principle of public key cryptosystem :- There are two basic principle of any cryptosystem one is confidentiality and second is authenticity.                                         1. Confidentiality To achieve confidentiality in asymmetric key encryption following key pair is used :           -For encryption receiver's public key is used.            -For decryption  receiver's private key i...
