Complete the code to identify the component that issues digital certificates in PKI.
The entity that issues digital certificates in PKI is called a [1].
The Certificate Authority (CA) is responsible for issuing digital certificates that verify identities in PKI.
Complete the code to name the key type used to encrypt data that only the owner can decrypt.
In PKI, the [1] key is used to decrypt data encrypted with the public key.
The private key is kept secret by the owner and is used to decrypt data encrypted with the corresponding public key.
Fix the error in the statement about PKI certificate expiration.
A digital certificate in PKI is valid indefinitely until revoked or [1].
Digital certificates have an expiration date after which they are no longer valid unless renewed.
Fill both blanks to complete the PKI process description.
When a user wants to send encrypted data, they use the recipient's [1] key to encrypt it, and the recipient uses their [2] key to decrypt it.
In PKI, the sender encrypts data with the recipient's public key, and the recipient decrypts it with their private key.
Fill all three blanks to complete the dictionary comprehension that maps domain names to their certificate status if the certificate is {{BLANK_3}}.
cert_status = { [1]: [2] for [1], [2] in certificates.items() if [2] == '[3]' }This comprehension creates a dictionary of domain names and their statuses, including only those with a 'valid' certificate.
