You, as a general, are free to assume typical ISPs in europe not secure and packet snooping possible, which means you must say DNSCurve insecure. Or, you, as an ordinary person, are free to assume typical ISPs in europe secure and packet snooping impossible, which means you must say simple nonce secure. Masataka Ohta
