[Batman] How public are the identities of all of Gotham city super criminals?

I'm writing a short fanfic idea, but for this idea to work I had to ask myself: are Gotham supervillains identities public knowledge? Can a teenager using the internet discover who they are with just a check on the In-universe wikipedia article?  


Of course, I know Joker nor Bane have an actual identity (the first one forgotten in time, the latter never obtained). but does the public know who Edward Nygma or Jonnathan Crane are?

Yeah, they're public knowledge- they are caught, unmasked and tried under their true names.

There are a few exceptions, but those who have been arrested have their real names known, at least to a "on their wikipedia page" level.
