There aren't many times where direct application of RSA's encryption transform, to recover semantically meaningful data, is useful. But widespread use of RSA predates modern crypto (what people used to call "Crypto 2.0", hallmark feature being authenticated encryption), so it's still in all the APIs.
Sadly, but unsurprisingly, searching for "Crypto 2.0" does not yield information about a shift in cryptography. What time period was this around when this phrase was being used? Where could I find more info on it? What was the shift primarily about?
That's a very good question. I heard it from Nate Lawson, and this would have been right around the time I wrote the [A-E-S "doing it wrong"] (just Google that) blog post. It's bugged me for years, too. I pretty sure he didn't make it up!
The big shift I perceived from him was from generic composition of authenticators and ciphers and such, and long sprawling discussions about E-t-M and M-t-E and "the Horton Principle" and stuff, to the AEAD ciphers pretty much everybody uses now.
