I was looking at the different types of SSL certificates and providers. I came across a website that states this:

We believe Extended and Business Verification SSL certificates gets more top rankings instead of Domain verification certs, but that is minor changes in Google algorithm

I searched Google but could not find any mention that the way a certificate is validated affects SEO (specifically with Google). I saw some websites suggest using a high key size for the certificate but I'm thinking that's for security?

Questions: Does Organization Validation (OV) and Extended Validation (EV) certificates get a better rank than Domain Validation (DV) certificates? What about the (RSA) key size?
