Hi there,

Can you tell me if you have support for SHA-2? In our automated scripts, we see the following in our logs:

Doing Diffie-Hellman group exchange
Doing Diffie-Hellman key exchange with hash SHA-1

I may be missing the setting on how to change this, so any help would be beneficial!

Thanks!

Yes, WinSCP supports SHA-256 (hmac-sha2-256).

Thanks for the response. Can you please tell me how I am able to choose this within the app? I seem to be missing how to do this.

See https://winscp.net/eng/docs/ui_login_kex

Though note that by default WinSCP prefers SHA-2. So it is likely your server that does not support/prefer it.
