Asymmetric cryptography transforms key distribution problems into key management problems.

Which is just a different problem, not necessarily an easier one, like you say.

That's a very nice way to put it, I'm going to reuse that !

more importantly, they're more cpu intensive and slow to deal with large files

Asymmetric encryption adds constant overhead, independent of message size.

Unless you're doing it wrong.

while not an expert I disagree, encrypt a 1GB file must be different from 1MB file, no matter it is sym or asym encryption. normally Asym is for keys while symmetric encryption is for the real content.
