Email Encryption Quiz

What is email encryption?

• The process of filtering email messages to remove spam.

• The process of compressing email messages to save storage space.

• The process of encoding email messages to protect the content from unauthorized access or interception.

• The process of decoding email messages to make them easier to read.

What is public key encryption?

• A cryptographic system that uses a single key to encrypt and decrypt data.

• A cryptographic system that uses two different keys, a public key and a private key, to encrypt and decrypt data.

• A method of encryption that does not use keys.

• A system that encrypts data using a combination of public and private keys.

How does public key encryption work?

• Public key encryption uses a single key for both encryption and decryption.

• Public key encryption uses a symmetric key for encryption and a public key for decryption.

• Public key encryption uses a private key for encryption and a public key for decryption.

• Public key encryption uses a pair of keys: a public key for encryption and a private key for decryption.
