Come on, the man's a legend!

Schneier designed Blowfish and was involved in the design of Twofish and Skein. When I was starting out, his book "Applied Cryptography" was both inspirational and informative, and I wouldn't be surprised if it was one of the most successful cryptography books ever written.

Schneier has also beeing blogging about security in general for decades; yes, sometimes he necessarily discusses government policy as a result, but I don't see what is wrong with that, or why that would make him a "hack" or "wonk".




Blowfish isn't good, and it's important never to use it (as a cipher; bcrypt is fine). But that aside: Schneier has had a weird aversion to elliptic curves, has never (that I know of) written anything technical about them, claims to "not trust the math" behind them (whatever that means), and my suspicion is that he simply hasn't studied them in any depth. All I said was: I wouldn't look to Schneier for information about curves.


Both of those are basically famous for being his work. They didn’t fare super well in the competitions they were submitted to. And they were collaborations, regardless.

His books are inspirational and somewhat informative. That means he is a successful author of cryptography books, not a successful cryptographer per se.


Blowfish predates the AES (and I believe he designed this one solo), Twofish was an AES finalist, and more recently Skein was a SHA3 finalist. I'd say his crpyptography credentials check out.

He’s a self-promoter. A valuable life skill to learn at some point is how to differentiate those who are legendary due to the awesomeness of their own feats, and those who manufacture legend from mediocrity.


That's pretty harsh, given his contribution to the field.

FWIW, I met him briefly at a developer conference in Norway a few years ago, and he actually seemed quite humble.
