How Asymmetric Algorithm works

Image
Asymmetric Algorithms are algorithms which are used to encrypt data that is needed to be transmitted from one PC to another over a network. These algorithms are used in " Asymmetric Cryptography " or " Public Key Cryptography ". Asymmetric Algorithms uses a Public key to encrypt the data(Plain text) before sending, and a Private key to decrypt it by the Receiver. Scenario There are 3 components taking part in this Scenario The objective in this scenario that if the User requests for a Web-page/Web service through the internet from a Server, the Server in turn should reply to the request of the User and then the User uses this service where transmission of (private)data can get involved. So is the reply/request communications between the user and the server secure enough, can any third party unauthorized person gain access to these data while transmission and spy/change/corrupt these data. Real life Example with the problems faced "You requ
