You have an email that you are sending to a friend. You want to ensure it retains its integrity during transit, so you decide to digitally sign the email. When using a PKI system, what is used to encrypt the hash digest of the email to create a digital signature?

Respuesta :

Answer:

Private key

Explanation:

A digital signature is created when a private key is used with the email document to generate a hash digest of the original email. The private key is used with a known public key, so even if an attacker sees the public key, he won't see the private one.

The hash digest is a randomly generated encryption line of text which makes no meaning until a private e is used to decrypt the text by the receiving party.
