I'm no judge of these apps, however a number of my remote friends use
signal for this type of thing and I'm a user as well. I was introduced
to it around the time of the Snowden revelations at a conference and
have been using it since for talking to a small set of people, mostly
because we can, not because of any special requirement.
It is cross platform, however it is designed for a smart phone to get it
started. After that, you can use desktop applications.

These scenarios are important ones.
One thing I've found with my own "emergency" tools is that they aren't
used enough so that they are up to date with other software and hardware
changes. That means that the tools have to be also part of regular usage
streams, even if somehow isolated from regular use. Or else there has to
be a regular test message, but that gets into the same problem the cell
phone "colour" alerts have. My wife and I think you could get elected
with 95% of the population if you promised (name your favourite TV
program)
would not be interrupted by the awful noise to let you know some kid
on the
other side of Ontario ran away from home. For us, it's that Jeopardy
answer
we want to hear.

Let me oopsify.
I asked what tools people here recommended for encrypted messages
"for personal use".
But I confused the issue by first asking if we wanted a secure
messaging solution for this group. Sorry!
One scenario: I would like to connect securely using my phone (text
for sure) with security people that I know on the webs, or in a
security consulting firm.
Another scenario: Connect (text, maybe voice) to outside security
people and co-workers during a security incident, when my work email
and my whole work machine, could be assumed pwned.

Let's remember this is a public list. If one wants to do secure
messaging, this is usually to a restricted list of recipients, each
with their own public key, regardless of the encryption or security
software. About having a shared keypair, the key is no more public.
And to encrypt the message to each and every of us, either the
sender has all public keys, or the mail relay has the ability to
decrypt the received message, and re-encrypt it to each and everyone
individually on the list.
As for verifying the authenticity of a given email, this means that
everyone has to sign it, and that anyone who wants to verify the
signature of a given message, the recipient needs to have the public
key of the sender, as well as some trust in this public key, beyond
just downloading it from a key server.

Hi
Re: "China-linked attacks on U.S. telecom networks"
Do we want to have a secure messaging solution for this group?
Is there a preferred encrypted messaging solution for personal use?
Tom's Guide has a report that seems useful.

Thanks!
