AFAIK it should be possible to make one key pair
and share both keys
with the whole list, just for use with this list. Everyone sends on
the public key and everyone decodes on the private key. Yes, it
technically violates the concept of key pairs, but we're just trying
to keep the list’s content from being easily [data collected] and
[censored] by [automated data collecting] mail providers(/entities).
I’m going to presume that any list encryption is pointless if
someone installs the key pair on anything except a local mail
client. E.g if someone installs the key pair on their google web
mail interface… (I didn’t think of this until later.)
That presumption is why I suggested a forum type of replacement for
the user lists. I’m not that up on current ‘stuff’ so pretty much
anything that eliminates [automated data collecting] being easily
tied to a particular person and/or an entity being able to [censor]
participation works for me.
I don’t think there is any sort of perfect solution (maybe a tor
onion site, but ugh, that wouldn’t be user friendly at all.).
The header is not encrypted, it's just the message body. So all
metadata analysis is still possible with an encrypted mailinglist. If
everybody uses kmail that's easy to fix with a filter - if you look at
my filter that I posted some days ago: if the mail is encrypted and
comes from e.g. "users-encrypted(a)trinitydesktop.org".org", then replace it
with the decrypted body. That body vcontains (violating the standard)
the whole message including headers. On the sending side
(mailinglist), just replace the header with a minimal version and
random subject (e.g. date+timestamp).
Making a shared private/public keypair for the list is used the othe
way round is no problem, as changing the private part will have no
effect. It's also convenient, as all users can use the public key to
send encrypted mail to the list. Again, kmail can handle this this
transparent for the user.
Oh, anybody needs a tutorial?
Yes Nik.
