In technical literature you often come across public and private keys being used for cryptography. In this article I will explain this concept. The whole concept of public and private key relies on the fact that you can create an encryption (public key) and decryption (private key) mechanisms that are totally independent of each other.
Suppose you have a box and the box has two keys, one for locking and another for unlocking. Suppose you distribute the key for locking to the entire world, it becomes a public key. So anyone can lock using that key and send stuff to you. But you kept the unlocking key to yourself (private key). So now even if some one intercepts that box, they can't open it.
