Question

bob sends alice an encrypted message using aes. what key would alice need to use to decrypt the message?

Answer 1

To decrypt an AES-encrypted message sent by Bob, Alice would need the same key that was used to encrypt the message, as AES employs symmetric-key encryption.

Step-by-step explanation:

If Bob sends Alice an encrypted message using AES (Advanced Encryption Standard), Alice would need to use the same key that Bob used to encrypt the message in order to decrypt it. AES is a symmetric-key encryption algorithm, which means the same key is used for both encrypting and decrypting the data. When Bob encrypts the message, he uses a specific key, and he must securely share this key with Alice so she can use it to decrypt the message and read the content.
