Explain about the Public Key Cryptography.
Public Key Cryptography:
It is a cryptographic system which uses two keys as a public key identified to everyone and a private or secret key identified only to the recipient of the message.
A significant element to the public key system is which the public and private keys are associated in such a way which only the public key can be utilized to encrypt messages and only the corresponding private key can be used to decrypt them. Furthermore, it is almost impossible to deduce the private key when you identify the public key.
They are really secure and relatively simple to employ.
