A company wants to allow external partners to send encrypted emails to its employees without requiring the partners to pre-share a secret key. The solution must also allow the company to verify the sender's identity. Which approach should the company implement?

Use a hash of the email content sent separately.

Use a symmetric key shared via a phone call.

Use S/MIME with certificates from a public CA.

Use a VPN tunnel for all email traffic.

A company stores sensitive customer data in a database. To protect the data at rest, the company decides to encrypt the entire database. Which key management practice is most important to ensure the security of this encryption?

Store encryption keys separately from the encrypted data

Share the key with all database administrators

Store the key in the same database as the encrypted data

Use the same key for all databases to simplify management

What is the primary purpose of a digital signature?

To compress the data for faster transmission

To encrypt the entire message so that only the recipient can read it

To convert the data into a fixed-size hash value

To provide authentication and ensure the integrity of the data

Two offices need to exchange encrypted files. They decide to use a symmetric encryption algorithm. What is the main challenge they will face?

Verifying the identity of the other office

Securely sharing the secret key between the offices

Ensuring the algorithm is fast enough

Generating a unique key for each file
