Assume that you use an encryption program that uses ChaCha$20$ to encrypt the same message two different times, using the same key during both times. Which of the following is true regarding the cipher text?

The cipher text from the two encryptions will be different. Even though the same key was used, the PRNG nonce will increment after the first message has been encrypted so the keystream for the second message will be different than the keystream in the first message.

The cipher text from the two encryptions will be different. Even though the same key was the PRNG counter will increment after the first message has been encrypted so the keystream for the second message will be different than the keystream in the first message.

The cipher text from the two encryptions will be the same since the same key was used.
