Encryption and Decryption

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
  • Public Key

Private Key: With private key cryptography, both communicating parties, use the same key to encrypt and decrypt the messages

Private Key Algorithm
  • AES
  • DES
  • DES3

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.
Public Key Algorithm

  • RSA
