SFTP SHA-2 ?

We are on WinSCP Version 5.17.5 (Build 10414)
Our financial vendors are asking for verification if our version supports sftp SHA-2
We have all our setups on sftp, but do not know if it's SHA-1 or SHA-2? Not sure how to find out.
Please let us know.
Thank you.

What "SHA-2"? There are many uses of SHA-2 in SSH.
