ENCRYPTION AND DECRYPTION
Encryption: It is a way to transform information to make it unreadable for unauthorized use
Decryption: It is a way to transform unreadable encrypted data back into readable
Key: It is a secret string
There is two type of key
Private Key: With private key cryptography, both communicating parties, use the same key to encrypt and decrypt the messages
Private Key Algorithm
Public Key: With public key cryptography, we use two key(public key, private key) for communicating over the network. We share public to other parties while private key keep secret by one party. The public and the private keys are cryptographic inverses of each other; what one key encrypts, the other key will decrypt.
Example: Suppose A want to send a message to B. A will encrypt the message with his private key and share his public key with B. B can decrypt the message with the public key of A.
