Smack 4.2.1 released

I've tagged and released Smack 4.2.1 to Maven Central. We decided to omit the smack-omemo* in this release packages as the API is not yet stable. Paul is currently working on encrypted Jingle Transports as part of his GSOC project which also involves OMEMO, and we probably will make some API changes to the existing OMEMO API because of that. As always daily snapshot builds are available from igniterealtime.org/repo.

Openfire 4.1.5 is released

The Ignite Realtime Community is proud to announce the 4.1.5 release of Openfire.  This release signifies our continuing effort to produce stable 4.1 series releases while work continues on the next major release.  A changelog denoting 18 resolved issues is available and you can download the release builds from our website.  There was one change that we decided not to ship with this release.  Work was done to produce 64bit windows installers, but complications exist when you attempt to upgrade previously installed 32bit versions.  We hope to iron out those issues prior to releasing 4.1.6 or even 4.2.0, depending on which comes first If testing this functionality interests you, please stop by our chatroom and let us know!

 

Important to know: Openfire now automatically installs the service. On the last step of the installer you will have an option whether to start it or not (it will also open the browser pointing to Admin Console, if you chose to start it). You shouldn't run the launcher, if the service is started. Documentation is updated accordingly. If you already have older service running, stop it before upgrading.

 

The following table denotes release artifact sha1sums and some github download statistics for the 4.1.4 release of that particular file.

Smack v4.2 Introduces OMEMO Support!

This blogpost doubles as a GSoC update, as well as a version release blog post.

I have the honour to announce the upcoming release of Smack! Version 4.2.1 brings among bug fixes and additional features like Explicit Message Encryption (XEP-0380) and Message Processing Hints (XEP-0334) support for OMEMO Multi-End-Message-and-Object encryption (XEP-0384). The OMEMO protocol was developed by Andreas Straub for the Conversations messenger (also as a Google Summer of Code project) in 2015. Since then it got quite popular and drew a lot of attention for XMPP in the media. My hope is that my efforts to develop an easy to use Smack module will result in an even broader adoption.

 

The new Smack release is available from the Maven snapshot repository.

 

OMEMO is a protocol for multi-end to multi-end encrypted communication, which utilizes the so called Double Ratchet algorithm. It fulfills amongst the basic requirements of encrypted communication (confidentiality, authenticity and integrity) also the properties of deniability and forward secrecy as well as future secrecy. Smacks implementation brings support for encrypted single and group chats including identity management and session renegotiation.

 

Current implementations (as well as this one) are based upon the libsignal library developed by OpenWhisperSystems for their popular Signal (formerly TextSecure) messenger. Smack's OMEMO support is structured in two modules. There is smack-omemo (APL licensed), which contains the logic specified in the XEP, as well as some basic cryptographic code. The other module smack-omemo-signal (GPLv3 licensed) implements some abstract methods defined by smack-omemo and encapsulates all function calls to libsignal.

 

Currently smack-omemo-signal is the only module available that implements the double ratchet functionality, but there has been a lot of discussion on the XMPP Standards Foundations mailing list regarding the use of alternative (more permissively licensed) libraries for OMEMO (like for example Olm, a double ratchet implementation from our friends over at the [matrix] project). So once there is a new specification that enables the use of other libraries, it should be pretty easy to write another module for smack-omemo enabling OMEMO support for clients that are not GPLv3 compatible as well.

 

Smack’s OMEMO modules are my first bigger contribution to a free software project and started as part of my bachelors thesis. I’m quite happy with the outcome

That was a lot of talking about OMEMO. Now comes the second functioning of this blog post, my GSoC update.

 

My project of implementing Jingle File Transfer (XEP-0234) for Smack is going relatively well. I'm stuck at some points where there are ambiguities in the XEP or things I don't know yet, but most of the time I find another construction site where I can continue my work. Currently I'm implementing stanza providers and elements needed for file transfer. Along the way I steadily create Junit tests to keep the code coverage at a high level. Already it pays off when there are fiddly changes in the element structure. I already got file transfer over Jingle IBB working.

 

It’s a real pleasure to learn all the tools I never used before like code coverage reports or mocking and I think Flow does a good job introducing me to them one by one.

 

That’s all for now. Happy hacking

Smack 4.2.0 released

Around two years ago, on 2015-03-29 to be precise, Smack 4.1.0 was tagged and released. A few days ago I've tagged and released Smack 4.2.0 to Maven Central. The 4.2.0 release marks a milestone for Smack, but before I got into the exciting new features, I'd like to thank the various contributors:

I can not remember when Smack had so many contributors. Thanks everyone and keep the contributions coming.

 

The notable changes to Smack 4.2 include support for DNSSEC (thanks to a previous MiniDNS GSOC project), JIDs as first class citizens by using JXMPP's JID API, and tons of other improvements, new features and bug fixes. You can read more in the Smack 4.2 Readme and Upgrade Guide and the Smack's JIRA release notes.

 

Last but not least, thanks to Bilal Siddiq, Smack now has a logo.

 

Ever wanted to contribute to open source? Are you interested in XMPP/DNS/DNSSEC? Google gives students the chance to work on open source projects and get paid for it as part of Google's Summer of Code 2017. The XSF acts as umbrella organization for projects like Smack and MiniDNS [4]. Feel free to contact me in the gsoc@muc.xmpp.org if you are interested in participating or if you want to discuss your own Smack/MiniDNS related project ideas.
