We have put an updated version of the Android Matrix Console app (v0.5.3) on the Play store!

This release mainly includes performance improvements, such as using the new "V2" sync API, and other optimisations which should make your user experience a lot nicer. There's also a few new features in the SDK (e.g. tags support) - these will be added to the app hopefully soon.

For the full list of changes, look at the CHANGES files in the android console and SDK projects

Get it from the Google play store!

Enjoy! And please do let us know your feedback in #matrix:matrix.org or #android:matrix.org!

So, you've installed an configured synapse and started chatting from your very own Matrix home server? What's the next step? Well, right now you're probably accessing your new home server over plaintext HTTP, which is bad, particularly because you'll be sending your password over this connection when you log in. You could connect to Synapse's secure HTTP port, but your browser won't trust it by default because you'd normally need to pay for a certificate that your browser would recognise. That is, until recently!

Let's Encrypt is a new initiative that issues SSL certificates free of charge, in an effort to make SSL universal on the Internet. In this blog post, we'll be walking through an example of how we can use this service to get ourselves a securely hosted Synapse.

We're going to assume you have a Synapse installed and listening on the standard ports, 8008 and 8448. If not, follow the Synapse README and come back here when you're done. Everybody ready? Okay, good.

So, in order to get a certificate from Let's Encrypt, we need to prove that we own our domain. The simplest way to do this is to host some special files on our web server. Now, Synapse won't do this. We could use a separate web server, but then we'd have to stop Synapse and start the other web server every time we renewed our certificate, and that means downtime. Instead, let's put our Synapse behind a proper web server and let that serve the files. This has added advantages, including that we can host our Matrix home server on the standard port 443 without having to run Synapse as root.

For this example, we're going to use NGINX, so start by installing NGINX in whatever way your Linux distribution of choice recommends.

Now, you should have a webroot for your new web server somewhere. Hopefully your helpful Linux distribution has started you off with a config file - let's see:

# nano /etc/nginx/nginx.conf

We're looking for the 'server' section of that file. We need to make it look something like this:

    server {'{'}
        # Make sure this is 0.0.0.0: no use listening on 127.0.0.1 or we'll only be
        # serving to ourselves! There's no port here, which means we'll listen on
        # port 80
        listen 0.0.0.0;

        server_name example.com www.example.com;

        access_log /var/log/nginx/example.com.access_log main;
        error_log /var/log/nginx/example.com info;

        # This is where we put the files we want on our site
        root /var/www/examplecom/htdocs;

        # Here's where it gets interesting: This will send any path that starts
        # with /_matrix to our Synapse!

        location /_matrix {'{'}
            proxy_pass http://localhost:8008;
        {'}'}
    {'}'}

When you're happy with the look of that file, let's restart the server:

# nginx -s reload

Before we go any further, let's test our new configuration:

$ curl http://example.com/_matrix/key/v2/server/auto
{'{'}"old_verify_keys":{'{'}{'}'},"server_name":"example.com","signatures":{'{'}"example.com":{'{'}"ed25519:auto":"RWb+w6vHUUokoDgElwG6Cg50ezZvBrzXtJmJIH8jEwI5x0JQ7prn3FwjhbgKTH5jE7J8Ily3HEc4COn4JCCvCA"{'}'}{'}'},"tls_fingerprints":[{'{'}"sha256":"DMbzSZ5Uj7/6p/RT/UtQYJLHm5o0TwBSVYXsqpDdVDs"{'}'}],"valid_until_ts":1455203001035,"verify_keys":{'{'}"ed25519:auto":{'{'}"key":"1YiTDjmE86AlmrbIYE2lyqauV9wPo8jw2kxZAZFfl/Q"{'}'}{'}'}{'}'}

Those are your server's public keys! Now we have a web server running, we can get our SSL certificate. Let's Encrypt have their own client which will automate everything including rewriting your NGINX config file, however that means it has a large number of dependencies and needs to be run as root. For this example, we're going to use the much simpler acme_tiny.py. I'm going to assume you have a user called, 'letsencrypt', so, as root, let's set up the place for it to write its challenge files:

# mkdir /var/www/examplecom/htdocs/.well-known/acme-challenge
# chown letsencrypt:users /var/www/examplecom/htdocs/.well-known/acme-challenge

Now let's switch to our letsencrypt user:

$ ssh [email protected]

We'll start by getting ourselves a copy of acme_tiny.py:

$ git clone https://github.com/diafygi/acme-tiny.git

Now let's set up a directory structure (let's say we might want to manage more than one domain someday):

$ mkdir examplecom
$ cd examplecom
$ ln -s /var/www/examplecom/htdocs/.well-known/acme-challenge challenges

Now, we'll need to generate two keys for Let's Encrypt, and account key and a domain key. The former is what we use to identify ourselves to Let's Encrypt and the latter is the key we use to do the actual SSL.

$ openssl genrsa 4096 > letsencrypt_examplecom_account.key
Generating RSA private key, 4096 bit long modulus
..++
.................................................................................................................................................................................................................................................................................................................................................................................................................++
e is 65537 (0x10001)
$ chmod 600 letsencrypt_examplecom_account.key
$ openssl genrsa 4096 > letsencrypt_examplecom_domain.key
Generating RSA private key, 4096 bit long modulus
.............++
.............................................................................................................................................................................................++
e is 65537 (0x10001)
$ chmod 600 letsencrypt_examplecom_domain.key

Now, store those keys somewhere safe! After you've done that, let's generate a certificate request for our domain. Note that we're requesting one for both example.com and www.example.com: this isn't strictly necessary for Matrix but could be useful if we want to host a website too.

$ openssl req -new -sha256 -key letsencrypt_examplecom_domain.key -subj "/" -reqexts SAN -config <(cat /etc/ssl/openssl.cnf <(printf "[SAN]\\nsubjectAltName=DNS:example.com,DNS:www.example.com")) > examplecom.csr

Okay, we have our keys, our certificate request, and somewhere to host our challenge files, so we're ready to request a certificate! Be careful about this part and make sure you've got everything right, because Let's Encrypt enforce strict rate limits on the number of certificates you can request for one domain. Here we go:

$ python ~/acme-tiny/acme_tiny.py --account letsencrypt_examplecom_account.key --csr examplecom.csr --acme-dir challenges/ > examplecom.crt
Parsing account key...
Parsing CSR...
Registering account...
Registered!
Verifying example.com...
example.com verified!
Verifying www.example.com...
www.example.com verified!
Signing certificate...
Certificate signed!

Is that it, did it work? Well, let's see:

$ openssl x509 -in examplecom.crt -noout -text
Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number:

    Signature Algorithm: sha256WithRSAEncryption
        Issuer: C=US, O=Let's Encrypt, CN=Let's Encrypt Authority X3
        Validity
            Not Before: Feb  6 21:37:00 2016 GMT
            Not After : May  6 21:37:00 2016 GMT
        Subject: CN=example.com
        Subject Public Key Info:
[etc]

Congratulations, you have an official, signed certificate for your domain! Now, before we can use it, we need to add the Let's Encrypt certificate to it, because our web server needs to send both:

$ wget https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem
--2016-02-06 23:38:55--  https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem
Resolving letsencrypt.org... 23.66.17.98, 2a02:26f0:60:489::2a1f, 2a02:26f0:60:481::2a1f

$ cat examplecom/examplecom.crt lets-encrypt-x3-cross-signed.pem >examplecom/examplecom_cert_chain.crt

Now's let's symlink it in place, along with the domain key, so we can renew it easily later. We'll need to be root again for this:

$ ssh [email protected]
# ln -s /home/letsencrypt/examplecom/examplecom_cert_chain.crt /etc/ssl/nginx/examplecom_cert.pem
# ln -s /home/letsencrypt/examplecom/letsencrypt_examplecom_domain.key /etc/ssl/nginx/examplecom_key.pem

Now, one more crucial thing we have to do before using our SSL is to give NGINX some Diffie Hellman parameters. This is a good thing to do for any SSL configuration (it will increase your score on SSL Labs) but it's absolutely crucial for us because Synapse will only negotiate forward secret connections, so otherwise other Matrix home servers will refuse to talk to us! (Technically, Synapse also support elliptic curve Diffie Hellman, which doesn't need DH parameters, but not all Synapses will support this.) You'll already have some Diffie Hellman parameters from you existing Synapse, so you could use them:

# cp /home/synapse/synapse/matrix.example.com.tls.dh /etc/ssl/nginx/examplecom_dhparams.pem

...or you can generate your own. You'll probably want to do this on your desktop or laptop if you have OpenSSL installed, it will be much faster:

$ openssl dhparam -out examplecom_dhparams.pem 2048
Generating DH parameters, 2048 bit long safe prime, generator 2
This is going to take a long time
........................................................+................[etc, etc]
$ scp examplecom_dhparams.pem [email protected]:/etc/ssl/nginx/examplecom_dhparams.pem

Now, let's get our new certificate in action! Open up your NGINX config file again, and add another server block that look like this:

    server {'{'}
        listen 0.0.0.0:443;
        server_name example.com www.example.com;
        ssl on;
        ssl_certificate /etc/ssl/nginx/examplecom_crt.pem;
        ssl_certificate_key /etc/ssl/nginx/examplecom_key.pem;
        ssl_dhparam /etc/ssl/nginx/examplecom_dhparams.pem;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        # mozilla intermediate list, jan 2016
        ssl_ciphers "ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:ECDHE-RSA-DES-CBC3-SHA:ECDHE-ECDSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA";
        ssl_session_cache shared:SSL:50m;
        access_log /var/log/nginx/examplecom.ssl_access_log main;
        error_log /var/log/nginx/examplecom.ssl_error_log info;
        root /var/www/examplecom/htdocs;
        location /_matrix {'{'}
            proxy_pass http://localhost:8008;
        {'}'}
    {'}'}

It looks pretty similar to our previous server block, except for all that stuff about SSL in the middle. We're pointing NGINX at our certificate, key and Diffie Hellman parameter files and specifying what protocols and ciphers we want our server to talk. The long list here is taken from Mozilla's Server Side TLS guidelines and is their 'Intermediate' list. See that page for more information on what that means, and choose a different list of ciphers if you prefer: just remember we must support at least the ephemeral Diffie Hellman ciphers, or other home servers won't talk to us!

Now let's restart our NGINX and see if it works:

# nginx -s reload

...and that command again, this time with https:

$ curl https://example.com/_matrix/key/v2/server/auto
{'{'}"old_verify_keys":{'{'}{'}'},"server_name":"example.com","signatures":{'{'}"example.com":{'{'}"ed25519:auto":"RWb+w6vHUUokoDgElwG6Cg50ezZvBrzXtJmJIH8jEwI5x0JQ7prn3FwjhbgKTH5jE7J8Ily3HEc4COn4JCCvCA"{'}'}{'}'},"tls_fingerprints":[{'{'}"sha256":"DMbzSZ5Uj7/6p/RT/UtQYJLHm5o0TwBSVYXsqpDdVDs"{'}'}],"valid_until_ts":1455203001035,"verify_keys":{'{'}"ed25519:auto":{'{'}"key":"1YiTDjmE86AlmrbIYE2lyqauV9wPo8jw2kxZAZFfl/Q"{'}'}{'}'}{'}'}

Hooray! You should now be able to open a browser to https://example.com/matrix/ and log in securely over SSL!

🔗Renewing Your Certificate

Now, there's one important step left, and that's to set up renewal for the certificate, otherwise we'll find our shiny new SSL will stop working in three months time. We can use the same acme_tiny command to do this:

$ python ~/acme-tiny/acme_tiny.py --account letsencrypt_examplecom_account.key --csr examplecom.csr --acme-dir challenges/ > examplecom.crt
Parsing account key...
Parsing CSR...
Registering account...

$ cat examplecom/examplecom.crt lets-encrypt-x3-cross-signed.pem >examplecom/examplecom_cert_chain.crt

Synapse will automatically pick up the new certificate, but we'll need to tell NGINX to reload:

# nginx -s reload

Setting up a cronjob to automate this is left as an exercise to the reader!

🔗Federation behind the HTTP Proxy

If you like, you can stop reading now: our clients can access our home server securely but other home server are still talking to our Synapse directly on port 8448. This is fine, and if you're happy with this, you can stop reading now. But remember how we made sure other Synapses could talk to our NGINX? Well, why not put federation behind our new web server too?

Now, we need to do a couple of things to make this work: were you looking carefully at the JSON those curl commands returned? If you were, you might have noticed a key called, 'tls_fingerprints'. Our home server serves up a fingerprint of the TLS certificate its using from this API, and we've just given our web server a different certificate, so we need to give Synapse our new certificate.

How are we going to tell other home servers to talk to our NGINX instead? Well, ultimately we're going to change our DNS SRV record to point at port 443 instead of port 8448, but that change could take a while to propagate through caches, so let's test it by having our NGINX listen on port 8448 temporarily. We can do this by copying that same block from above, but with a different port:

    server {'{'}
        listen 0.0.0.0:8448;
        server_name example.com www.example.com;
    [etc]

Don't restart NGINX just yet: we need to tell our Synapse to stop listening on that port first, so lets do that and give it our new certificate:

$ nano /home/synapse/synapse/homeserver.yaml

Now we'll want to find and edit the following lines:

tls_certificate_path: "/etc/ssl/nginx/examplecom_crt.pem"
# We can comment this out, as long as we set no_tls to true below
# tls_private_key_path: "/whatever/path/synapse/generated"
# PEM dh parameters for ephemeral keys
tls_dh_params_path: "/whatever/path/synapse/generated"
# Turn off TLS everywhere (this overrides the listeners section below)
no_tls: True
  - port: 8008
    tls: false
    # We can bind to only localhost since only the local nginx needs to hit this
    bind_address: '127.0.0.1'
    type: http
    # Set this so that Synapse obeys nginx's X-Forwarded-For headers, then IP addresses will be correct in Synapse's logs
    x_forwarded: true
    resources:
      - names: [client, webclient]
        compress: true
      - names: [federation]
        compress: false

Note: if you have an old enough config file that you have 'bind_host' and 'bind_port' directives, now is the time to remove them.

Now let's restart Synapse and our web server to swap over what's listening on our port 8448:

$ synctl restart
# nginx -s reload

Now let's try that test again on port 8448:

$ curl https://example.com:8448/_matrix/key/v2/server/auto
{'{'}"old_verify_keys":{'{'}{'}'},"server_name":"example.com","signatures":{'{'}"example.com":{'{'}"ed25519:auto":"bdca31805e4209f6ff4d644251a29d0cb1dc828a4d6131c57cf8305288f337c0"{'}'}{'}'},"tls_fingerprints":[{'{'}"sha256":"1d9ec66599e229654a79f28e26675fdeb585027553af6d581926e821a6b6527c"{'}'}],"valid_until_ts":1455203001035,"verify_keys":{'{'}"ed25519:auto":{'{'}"key":"1YiTDjmE86AlmrbIYE2lyqauV9wPo8jw2kxZAZFfl/Q"{'}'}{'}'}{'}'}

Notice anything different? The tls_fingerprints part has changed because we now have a different certificate. The signatures/example.com/ed25519:auto value has changed too: that's because that part is a signature of the rest of JSON object, so changing the tls_fingerprints has caused this to change too.

And that's it! If you're happy everything is working, you can then change your DNS SRV record to point at port 443 instead of 8448, then after leaving a few days for the change to propagate through caches, remove the extra server block from your nginx.conf and restart to stop your nginx listening on port 8448.

Hi all,

Synapse 0.13 was released this afternoon, bringing a new wave of features, bug fixes and performance fixes. The main headlines include: huge performance increases (big catchup /syncs that were taking 20s now take 0.3s!), support for server-side per-room unread message and notification badge counts, ability for guest accounts to upgrade into fully-fledged accounts, change default push rules back to notifying for group chats, and loads of bug fixes. This release incorporates what-was 0.12.1-rc1.

Please note that on first launch after upgrading a pre-0.13 server to 0.13 or later, synapse will add a large database index which may take several minutes to complete. Whilst the index is added the service will be unresponsive.

Please get the new release from https://github.com/matrix-org/synapse and have fun!

Matthew

Full release notes:

こんにちは

Matrix is on its way to Japan where Kegan is attending the TADHack-mini (Feb 13th and 14th) and WebRTC Conference (Feb 16th and 17th).

Kegan will help hackers with their projects during the TADHack, but first, he will give a talk on Matrix and how it can be used. We are again awarding a trossen robot to the best hack using Matrix, and we are as always curious to see what kind of cool and crazy ideas people will come up with!

A couple of days later, Kegan will be giving a talk during the WebRTC Conference: "The missing signalling layer for WebRTC".

Both of the talks will be live-translated, and there will also be a translator available during the events, so please come and say hello to Kegan-san! As always, we are also available in the Matrix HQ room, via a client like Vector or any other client!

The Matrix team had a very successful trip to FOSDEM '16 last weekend. Many, many words were exchanged, and at times there was a queue of people just waiting to have a chat! We spoke to a whole lot of interested and interesting people, some of which had heard of Matrix already, and some who hadn't. The nice thing with the crowd at FOSDEM is that they very quickly "get" what we're trying to do with Matrix - and then start thinking aloud about how they might want to use it or extend it - which means we have many great conversations!

At the beginning of FOSDEM, I think we had around 2000 people "currently" in the Matrix HQ room - the next day, that number had increased by a hundred (and now it's even bigger due to a hackernews post where we mentioned Matrix)!

Our talk in the IoT dev room was very popular; unfortunately a lot of people that were queueing to get in never made it due to the limited space. However, the talk was recorded, and it's already been made available:

You can also look at the slides from the talk. Note that due to technical problems, the first half of the talk was not recorded.

We also did a talk in the Real Time dev room, which was equally popular. Hopefully the video from this talk will also be available shortly (you can keep an eye on the video repository for this dev room) - once it is, I will add it to this post.

For now, you can look at the slides from the talk.

Another interesting talk where Matrix ended up being represented, was Daniel Pocock's Improving Telepathy talk. I'll add the video from that too, once it's available.

Finally, thanks to everyone who came to say hello and have a chat - and to everyone who has since set up their own homeserver. Please do join the Matrix HQ room (using any of these clients) and let us know how your Matrix experience is going!

Matrix will again be represented at FOSDEM (Free and Open Source Software Developers' European Meeting) in Brussels, Belgium, January 30th and 31st. This year, we have two talks scheduled: one in the IoT devroom on Saturday at noon, and one in the Real Time devroom at 3.10pm the same day.

We also have a stand on the 2nd floor of the K building - next to the Real Time lounge (potentially same spot as last year). If you're going to FOSDEM, please come and say hi to us at the stand or at the talks!

Our trip to FOSDEM '15 was very enjoyable; we met a lot of smart people and learnt about a lot of interesting technologies and projects. Hopefully we made a few people enthusiastic about Matrix as well!

As always, for any questions or comments, please come talk to us in the official Matrix HQ room - you can join via any of these clients (or write your own!).

Happy 2016 everyone!

To greet the new year, we bring you all new Synapse 0.12. The focus here has been a wide range of polishing, bugfixes, performance improvements and feature tweaks. The biggest news are that the 'v2' sync APIs are now production ready; the search APIs now work much better; 3rd party ID invites now work; and we now mount the whole client-server API under the /_matrix/client/r0 URI prefix, as per the r0.0.0 release of the Client Server API from a few weeks ago. The r0 release unifies what were previously the somewhat confusing mix of 'v1' and 'v2' APIs as a single set of endpoints which play nice together.

We highly recommend all homeservers upgrading to v0.12.0 as soon as possible. Get it now from https://github.com/matrix-org/synapse/ or via our shiny new Debian packages at https://matrix.org/packages/debian/.

Full changelog follows:

🔗Changes in synapse v0.12.0 (2016-01-04)

• Expose /login under r0 (PR #459)

🔗Changes in synapse v0.12.0-rc3 (2015-12-23)

• Allow guest accounts access to /sync (PR #455)
• Allow filters to include/exclude rooms at the room level rather than just from the components of the sync for each room. (PR #454)
• Include urls for room avatars in the response to /publicRooms (PR #453)
• Don't set a identicon as the avatar for a user when they register (PR #450)
• Add a display_name to third-party invites (PR #449)
• Send more information to the identity server for third-party invites so that it can send richer messages to the invitee (PR #446)
• Cache the responses to /initialSync for 5 minutes. If a client retries a request to /initialSync before the a response was computed to the first request then the same response is used for both requests (PR #457)
• Fix a bug where synapse would always request the signing keys of remote servers even when the key was cached locally (PR #452)
• Fix 500 when pagination search results (PR #447)
• Fix a bug where synapse was leaking raw email address in third-party invites (PR #448)

Hi all,

We've been pretty bad at updating the blog over the last few months with all the progress that's been happening with Matrix. Whilst Matrix rooms like #matrix:matrix.org and #matrix-dev:matrix.org have been very active (and our twitter account too), in general we've ended up spending way too much time actually writing software and not enough time talking about it, at least here. When a blog goes quiet it normally means that either the authors have got bored, or they're too busy building cool stuff to keep it updated. I'm happy to say that option 2 is the case here!

As a result, there's a huge backlog of really cool stuff we should have talked about. Hopes of writing an Advent Calendar series of blog posts also went out the window as we set Christmas as an arbitrary deadline for loads of work on Synapse, the Matrix Spec and matrix-react-sdk.

So, to try to break the impasse, here's a slightly unorthodox whistle-stop tour of all the amazing blogposts we would have written if we'd had time. And perhaps some of them will actually expand into full write-ups when we have more time to spare in the future :)

Matrix will again be represented at the WebRTC Conference & Expo in Paris. Daniel and myself are catching the Eurostar tomorrow afternoon, and the conference will start early Wednesday morning with a panel about WebRTC for Mobile, where Daniel is one of the participants.

I'm sure we will have three days full of interesting talks and discussions (see the full schedule here). There will be demos as well, and Matrix is (of course!) also joining the demo competition. We hope to see many familiar faces - and hopefully meet some new ones as well!

If you are going to the conference, please come and say hello – we will have a stand at the expo (we're table #6 - see map here). And don't miss Daniel's Matrix One-year Status Report at 11.10am on Friday!

See you there!

Matrix will be represented at the 32nd Chaos Computer Club, Dec 27th-30th, 2015. We hope to be arranging an assembly, where people can come along to learn about Matrix and our recent work on end-to-end encryption, find out what they can use Matrix for - and also do some hacking at the same time!

UPDATE: We've snagged a table for the assembly at: "hackcenter room with C-base, a table along the pathway". In practice only Mjark is there from Matrix and may be moving around, so may be easiest to coordinate meetups via #32C3:matrix.org

The session is free of charge, although you do need a ticket to the Congress itself.

If you are interested, please register by sending an email to [email protected]. All you need for the session is curiosity - but do bring your own laptop if you want to hack as well!

Anyone is welcome to join - it will basically be a fairly open-ended chat about all things relating to Matrix, and a good chance to do some deep digging into Matrix itself.

Hope to see you there!
