No. Discussion was at some point about reasons of using strong crypto.
And at some point idea that it's not worth to use it against data which
has no value appeared. My point is you are not in the position to say
what's the value of the data someone is encrypting. You weren't reading
carefully enough to see this and you are suggesting me that I'm trying
to force GnuPG authors to do something which is - almost offensive -
rubbish. This is discussion Peter, nothing else.

In overall I agree with this but "disabling all stuff but AES256" is
silly and overdrawn try to devaluate my statement.

If you can't afford this "immense" expense - don't use 8k RSA.

You are following idea that people who are using strong crypto to things
which are in your opinion worthless aren't serious.
Looks like at best you replied to piece of thread without knowing its
There is a difference between your overdrawn (again) interpretation that
all this data is without value in eyes of GnuPG authors. I'm just saying
that it's not for them do evaluate value of this data. Simple as this.
And yes - by using extremely cheap rhetoric tricks you made this opinion
yours. I'm really sorry because of you but this is not my problem.

At some point discussion was quite constructive but it's not anymore.
