I've heard people talk about ed25519, though I'm not sure it can be used for encryption.\n\nDoing ECDH with our curve is within a factor of ~2 of the fastest\nencryption available at this security level, AFAIK.  And separate\nencryption would ~double the amount of data vs using the ephemeral key\nfor derivation.\n\nUsing another cryptosystem would mandate carry around additional code\nfor a fast implementation of that cryptosystem, which wouldn't be\nfantastic.\n\nSo I'm not sure much can be improved there."}
