In a public-key file-encryption workflow, the private key is used to _____ the encrypted file.
Answer
decrypt
Explanation
### Why this is right
The private key is the matching key used to reverse encryption performed with the recipient's public key.
### The concept
Encryption transforms readable data into ciphertext. Decryption reverses that transformation for someone with the correct key. In public-key confidentiality, the public key encrypts and the corresponding private key decrypts.
### Remember
Public key encrypts; matching private key decrypts.
