PGP, digital signature, disk encryption etc. So here we can conclude that encryption plays a vital role in our day to day life to secure our digital or virtual life. WebIf the lock/encryption key is the one published, the system enables private communication from the public to the unlocking key's owner. If the unlock/decryption key is the one published, then the system serves as a signature verifier of documents locked by the owner of the private key. This system also is called asymmetric key cryptography.

WebMACs differ from digital signatures as MAC values are both generated and verified using the same secret key. This implies that the sender and receiver of a message must agree on the same key before initiating communications, as is the case with symmetric encryption . WebA message digest created using a secret symmetric key is known as a Message Authentication Code (MAC), because it can provide assurance that the message has not been modified. The sender can also generate a message digest and then encrypt the digest using the private key of an asymmetric key pair, forming a digital signature.
