Whats the round amount for SHA512 in Exercise 09 Task 1?

Question

We are supposed to compute the SHA512 hash value over the string Web-SeCuRiTy-2026. When I try this task with CyberChef I can also adjust the round amount. The default in CyberChef is 160 but when I search the internet I find 80 as default. Which amount of rounds should we use?

Answer 1

You should use the SHA-512 with its regular amount of rounds. You can double-check with other SHA-512 implementations to verify that you chose the correct number.
