Isn't it scary if the server does not allow a query cancel? For example, if the server charge you per query duration and if you accidentally send a long running query, the only escape exit is the query cancellation. > It's also worth thinking about the new protocol 3.2 longer key data. > A paranoid server might choose to send key data only if protocol >=3.2 > is chosen and not if a lower, notionally less secure version is > chosen. I would say the server does wrong a decision. I think even if the key is not long, it's still useful than nothing. Best regards, -- Tatsuo Ishii SRA OSS K.K.
