COMPUTER FUNDAMENTALS

Detailed explanation-1: -The sender uses a private key to encrypt the message while the receiver uses the public key of the sender to decrypt the message. In Digital Signature, the private key is used for encryption while the public key is used for decryption. Digital Signature cannot be achieved by using secret key encryption.

Detailed explanation-2: -A private key is used by the sender to encrypt the data and send the digital signature. As the name suggests, the private key is kept secure in the sender’s hardware and is known only to the sender. The recipient uses the sender’s public key to decrypt the message.

Detailed explanation-3: -In cryptography, a key is a value used with an algorithm to encrypt and/or decrypt data. A private key, also known as a secret key, is kept on its owner’s system and never transmitted publicly. A public key, as the name implies, is openly available to anyone who wants it.

Detailed explanation-4: -Digital signatures To digitally sign a message, the sender would generate a hash of the message, and then use his private key to encrypt the hash, thus generating a digital signature. The sender would then send the digital signature along with the message, usually by appending it to the message itself.

Detailed explanation-5: -Share to Facebook Share to Twitter. Definition(s): A cryptographic key that is used with an asymmetric (public key) cryptographic algorithm and is associated with a public key. The private key is uniquely associated with the owner and is not made public.
