The answer to that, of course is - "OK - so how many per day can they do
that to, and why should MY message be in the top-priority x out of the
number they are likely to wish to brute-force, rather than say someone
likely to be suspected of links to ObL?"

Well, not provided they haven't got some specific and compelling purpose
in targeting you, personally, or your server, specifically.
Tinfoil hat apart, the ability of "them" to break any particular crypto
in any timeframe longer than seconds, or more likely milliseconds, means
that it has to remain a solution directly targeted by other intelligence
or objectives.
