• Public key

• Digital signature

"The same key used to encrypt the data is sent through the network and used in the server side to decrypt the data"

This is known as:

• TLS Certificate

• Key

• Symmetric encryption

It uses a pair of keys, a private key and a public key.

What type of encryption does the above statement refer to?

• Asymmetric encryption

• TLS Certificate

• Key

• Symmetric encryption

The public key (ID_RSA.pub) should be added to the ______________file at the server's side.

• ~/.ssh/authorized_certs

• ~/.ssh/server_keys

• ~/.ssh/authorized_keys

• ~/.ssh/authorized_keys_file

You have the following information, use them to SSH a server:

Private key: id_rsa

User: user1

Server: server1

Create a private key at the server's side. Name it "my-bank.key" with a lenght key 1024

You previously created the private key "my-bank.key".

Use that private key to create a public key named "mybank.pem".

They're well known organizations that can sign and validate your certificates for you.

• CA

• IANA

• PKI

It's the whole infrastructure, including the CA, servers, people and the process of generating, distributing and maintaining digital certificates.

• ISPs

• DNS

• CA

• IANA

• PKI

Usually, certificates with public key are named ________ or _________ extension.
