Select ALL components of the hybrid encryption process demonstrated in the lesson.

### Why this is right - **Encrypt the document with a symmetric key.** The lesson uses a symmetric key for the file itself. - **Encrypt the symmetric key with the recipient's public key.** This protects the key so only the recipient can recover it with the matching private key. - **Send the encrypted document and encrypted key to the recipient.** Both are needed for the recipient to recover the file. ### The concept Hybrid encryption applies symmetric encryption to the document and asymmetric encryption to the symmetric key. The recipient first decrypts the key with a private key and then decrypts the file with that recovered key. The public key is used to encrypt the symmetric key, not to decrypt the file. ### The other options - **D. Use the recipient's public key to decrypt the document.** This is wrong because the file is encrypted with the symmetric key; the public key protects the symmetric key. ### Terms - **Symmetric key**: A shared secret used to encrypt and decrypt the file. - **Public key**: A shareable key used here to encrypt the symmetric key. - **Private key**: The recipient’s secret key used to recover the symmetric key. ### Remember The public/private pair protects the symmetric key, not the document in this hybrid workflow.
