You want to send to your bank the message "Transfer 200 dollars from account 314276 to account 135224". To guarantee message integrity, you and your bank share the secret 314159.

Assuming the secret is appended at the end of the message and then a MAC is computed using SHA-256, what would be the MAC that would be sent to the bank along with the message ?

You can login to computer science to compute SHA-256 using the command sha256sum or use an online SHA-256 calculator.
