This article was published in 2018 about R&D work, which resulted in stable production release of Themis that now uses OpenSSL 1.1.1g If you’re a developer and you’re dealing with cryptography for your app, consider using high-level cryptographic libraries like Themis instead of OpenSSL. No need to struggle with OpenSSL if your goal is to protect users’ data. Moving to OpenSSL 1.1.0 Besides introducing breaking changes through abandoning backward compatibility on x64 systems, the recent version of Themis (Themis 0.

ACRA 0.76 RELEASE The spring and change are in the air! After a year in testing by early adopters (Acra 0.75 was released 1 year 5 days ago), we’re starting to push new features into the open-source version of Acra. 0.76 is a stability release, which unifies a lot of things “under the hood”: module interfaces, test automation, API, connection schemes — everything we need to gradually unveil & plenty of new exciting features we’ve prepared based on the user feedback.

THEMIS 0.10.0 RELEASE We couldn’t hold out till St. Valentine’s Day, so we’re releasing the love and all the hard work put into the new version of Themis today. Themis 0.10.0 is out and there is no turning back as this release introduces breaking changes. If you are using Themis on x64 systems, consider upgrading every Themis library/wrapper you were using to 0.10.0. Incompatibility issues may arise between previous Themis versions and 0.

Stats This was an eventful year for Cossack Labs! According to our GitHub stats, in 2017 we: made 1200 commits into master branches; merged 260 PRs; accumulated 444 new stars. Products and releases We picked a weird, but hopefully auspicious habit of releasing stuff on holidays or 13th days of the month (preferably Fridays :) or Mercury retrograde periods: Acra Acra’s public release took place on the 8th of March.

Season’s greetings and all kinds of good things in the New Year! – With 🔒 from Cossack Labs!

THEMIS 0.9.6 RELEASE One release a week is good, two releases is better still. After releasing Hermes-core 0.5.1 PoC yesterday, following the good tradition of releasing on the 13th day of the month, we’re releasing Themis 0.9.6 today. The main feature of this release is adding support for OpenSSL 1.1. The rest of the update details are as follows: Docs: Significant update of the Contributing section in Wiki.

Hermes by Cossack Labs Cossack Labs release a proof of concept version of Hermes — a framework for cryptographically assured access control and data security. A PoC reference implementation of Hermes is Hermes-core 0.5.1, the source code and accompanying documentation of which become available on December 13, 2017. What is Hermes Hermes is a cryptography-based method of providing protected data storage and sharing that allows enforcing cryptographically checked CRUD permissions to data blocks and doesn't let server that's running Hermes do anything worse than DoS.

Intro Like death and taxes, one thing that you can be sure of is that using C macros in a modern software project will cause a debate. While for some macros remain a convenient and efficient way of achieving particular programming goals, for others they are opaque, introduce the unnecessary risk of coding errors, and reduce readability. The criticism of macros is particularly acute in the wider security community. Among Cossack Labs’ engineers and the core Themis crypto library contributors there are people who previously worked on auditing cryptographic implementations of critical code.

This article was published in 2017 about R&D work, which resulted in stable production release of Themis. Intro In our ongoing effort to make Themis work with different cryptographic backends, we've decided to try something more challenging than just displacing similar primitives. This time we decided to make Themis work on Daniel J. Bernstein’s cryptography, as it is introduced in NaCl. What if one day it turns out that Daniel Bernstein’s assumptions about the rest of the world are correct, and everybody else is a lunatic?

THEMIS 0.9.5 RELEASE Strategic planning, respect for traditions, and a consultation with our in-house astrologer led to an imminent release of Themis 0.9.5 on Wednesday 13, the 256th day of the year a.k.a. the International Developer’s Day. The update focuses on crystallizing conveniences, niceties and compatibility fixes that have been around for some time now. Here is the list of improvements: Infrastructure: You can now download pre-built Themis packages from our package server.
