[Star Wars]What did the Galactic Public know about Darth Vader?

So, I'm assuming that the official line was that Anakin Skywalker died in the Jedi Rebellion, either being killed by his clones or by the Jedi for not siding with them.

So, what's the public's reaction when Palpatine names this random guy in a black suit commander of the Imperial Military? I assume that anyone with a sliver of historical knowledge would know that "Darth" Vader is either a Sith or has aspirations of being one, and Vader wasn't exactly shy about using his lightsaber/force powers. 

Related, would the public *care* that Vader was a Sith? And did anyone know that Palpatine was his master?

The general public knows he's a cyborg in a very high place in the Empire. There's even been songs written about that.

But the Sith aren't known about at all, except by historians and Jedi. None except the innermost circle of Palpatine know the truth.
