Add usage example to README about go-ipns HOT 4 CLOSED

Oh, I just looked and realized libp2p-crypto already has GenerateKeyPair(), which does exactly that :P
Are there any concerns with that, or is this perfectly fine?

That should work. We often specify a "test" source of randomness to make the tests faster but we really shouldn't be doing that in examples.

Also, we should probably use a 2048 bit key (instead of 1024 bits). Every time we use 1024, we should explicitly say "not safe for production use".

Happy to propose a PR with the above if that’s good, but it would be nice if we could do the key generation without relying on two other packages.

Well, we don't really need go-ipfs-util (can use crypto/rand.Reader). However, key generation is a separate concern so will probably require the additional import.

privateKey, publicKey, err := crypto.GenerateKeyPair(crypto.RSA, 1024)

Oh, d'oh, I guess it has to be a Libp2p PrivKey, so you can’t really get away from that requirement. Boo to me for not looking that up first. 👍
