**Entropy sources:** Rust OsRng, password generator, various texts, obligatory keyboard mashing.

**Time taken:** 10,5 hours

**Side channel defenses:** None.

**Postprocessing:**

- I ran `verify_transform_constrained` which confirmed the computation went correctly and printed the challenge, response, and new challenge hashes above.

- I uploaded the response to an SFTP server provided by Wei Jie Koh.

- I logged out/in, ran some ad-hoc memory filling script for good measure, and turned off the server.

- Signed this file using keybase (`naure`), made a PR on github (`naure`).
