Question
Digital certificates are used for what purposes? (Select two.)1 pointHashingSymmetric EncryptionAsymmetric EncryptionIdentification
Solution
Digital certificates are used for:
-
Asymmetric Encryption: Digital certificates are used in asymmetric encryption to encrypt and decrypt the data. They contain the public key for a certain user or entity and allow others to encrypt data that only the user/entity can decrypt with their private key.
-
Identification: Digital certificates are also used for identification purposes. They provide a way of verifying that a public key belongs to a certain user or entity. This is done by a trusted third party, known as a Certificate Authority (CA), which verifies the identity of the user/entity and then signs the certificate. This allows others to trust that the public key really belongs to the person/entity it claims to belong to.
