a. created by hashing a document and then encrypting the hash with the signer's private key
b. created by hashing a document and then encrypting the hash with the signer's public key
c. created by hashing a document and then encrypting the hash with the signer's symmetric key
d. none of the above

Answer 1

A. created by hashing a document and then encrypting the hash with the signer's private key.

Step-by-step explanation:

Digital signatures are created by the process of writing an encrypted message, which will represent the signature of someone; it is also created another key that will be public. This is a very secure method, because any document will be encrypted with their private key , but someone will be able to open it if they have the public key corresponded to the signer's personal key.
