Hi Jelbert.
Exchanging by usb stick you give personally is safe.

Mail and forums are very unsafe. You can make mail safe however by 
using GPG, you and your friend both need to use it.

You need eachothers public key, you use it to encrypt mail only you 
and your friend can read.
You can sign your message by your secret key, your friend knows for 
sure the message is by you.

Not even the NSA is known to be able to crack GPG.

I think everyone who is privacy-aware must use GPG as much as he 
can.

I am privacy aware, for that reason this is an anonymous mail.
The NSA stores the text (yes they do!), but they can not know who 
sent it.

(Sorry for the long delay in answering this, we've been a volunteer-only 
project for the past >6 months. No employees to be forced to reply to 
mails...)

What is "safe" depends on who you think might be attacking you.

In theory, people who are capable of intercepting your mails could replace 
your noderef with their own and thus intercept your Freenet traffic.
This is called man-in-the-middle attack:
   https://en.wikipedia.org/wiki/Man-in-the-middle_attack

Of course this is a bit complex to do and thus will probably only happen if 
someone is actively trying to hack you, such as a government.

So if you don't feel like the government is interested in you personally, use 
mail. Otherwise use an USB stick.

[freenet-support] safe to send noderef by email

2016-05-15 Thread jelbert nl
Hi,

If I want to invite friends to freenet would it be safe to exhange the noderef 
bij email or exhange them on a forum? Or is the only secure way to exhange them 
by a physical meeting and excange usb sticks?


Cheers,

Jelbert

Yes but it takes time (and many CAPTCHAs) to announce a new identity. :|

[freenet-support] safe?

2011-02-20 Thread folkert
Hi,

If I understand correctly, also the local cache and all files and such
are encrypted, right? And you can only access them if you know the key
you're looking for.
How is that with fms? If I read a message in it and it is cached on
local disk (is it?) is it encrypted?

The sqlite3 (fms.db3) file. It contains all your options/identities, as
well as saved forum messages and trust lists. It probably would be
handy if it could be stored already encrypted on disk, but as you
suggest, it's not essential. I don't think you can change where it gets
saved -- not even via (sym)linking. (Because, I think, when it
defragments the database, it recreates and overwrites the existing db.)

Hmmm ok.
Problem with that is that one can be persuaded to give encryption
keys.
