Fundamentals of InfoSecintermediate
Place the recipient's steps for decrypting a hybrid-encrypted message in the correct chronological order.
Answer
Receive the ciphertext and the encrypted symmetric session key, Decrypt the symmetric session key using the recipient's private key, Decrypt the ciphertext using the recovered symmetric session key
Explanation
### The order
1. **Receive the encrypted file and the protected symmetric key**: the recipient needs both encrypted components to continue.
2. **Use the recipient's private key to recover the symmetric key**: only the matching private key performs this step for the recipient.
3. **Use the recovered symmetric key to decrypt the file**: the symmetric key was used to encrypt the data.
### Remember
A hybrid recipient must recover the data key before decrypting the data.
