5d41402abc4b2a76b9719d911017c592. Use that as a smoke test.

Should I hash passwords with MD5?

No. MD5 is broken for collision resistance. Use a password KDF. This page still shows MD5 because people search for checksums.

How is SHA-256 computed?

With the browser Web Crypto API. MD5 is a local RFC 1321 implementation because Web Crypto does not include MD5.

Type or paste text.
Copy MD5, SHA-1, or SHA-256.
Prefer SHA-256 unless you are matching a legacy checksum.

Worked example

Input hello must produce MD5 5d41402abc4b2a76b9719d911017c592 and SHA-256 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824. The SHA-256 page is the same widget aimed at the SHA query; HMAC-SHA-256 is for a keyed message.
