Questions

Is my file uploaded to compute the hash?

No. The browser's own Web Crypto reads the file on your device. Nothing is sent anywhere.

Why is SHA-256 the default?

It is the hash most software publishers use today. SHA-1 is offered only to match older published hashes.

Can I get MD5?

No. Browsers do not offer MD5 in Web Crypto, and it is not safe for checking files. Ask the publisher for a SHA-256 hash.
