Introducing Acra If you are concerned about data security, this means confronting a threat landscape that requires vigilance and defence against a wide range of attacks. One of the prime targets for attack continues to be sensitive data that is stored in backend database storage. From simple discovery of unsecured databases, through classic SQL injection techniques, to compromised infrastructure that allows wholesale copying of database content, attacks focus on data assets with increasing precision.

Intro Themis provides several methods for encrypting data at rest - Secure Cell, Secure Message. Where do people store data? In files and in databases. Sometimes, you want to manipulate cryptographic data on the database side, this is where Themis plugins come handy. Even though generally it's a questionable practice, but sometimes you need to encrypt/decrypt data on the database side. Moreover, there are some security designs where you have to:

Why feel cold when happiness and laughter of your colleagues might make any evening warm and happy. Yesterday our team gathered to  release Themis 0.9.4, and so did we.  Take a look at the updates: BoringSSL support on Android and Linux Fixed some leaks and code styling problems (thanks to @bryongloden) Memory management updates for stability in languages, which rely on GC Fix Themis build errors under certain conditions Swift3 support + numerous enhancements from @valeriyvan GoThemis: fixed rare behavior in Secure Session wrapper

More than half of the year has passed since the last release and we have done a lot to make Themis better. Here is what we have updated: Infrastructure: Lots of new high-level language wrappers Enhanced documentation We have added lots of various demo projects Updated Themis Server Better make system verbosity (now you can see what succeeded and what didn't) Infrastructure to build Java on all platforms. Code:  iOS wrapper now has umbrella header.  We have added Swift language examples and howto.

Intro Themis server is a sandbox for developers, who want to test Themis features without spending too much time and effort. You don’t have to deploy client and server, as you can find it on themis.cossacklabs.com and dive straight into using library, with handy examples. Themis server gradually evolves, so some slight differences in button placement are possible over time (as they happen at the time of writing), yet core functions will remain unchanged.

What is WebThemis WebThemis enables web app developers to build browser applications with strong cryptographic services, provided by Themis cryptographic library. Currently, WebThemis works in Google Chrome as PNaCl module; it can be loaded during a regular web session, or used as a library within Chrome App. WebThemis provides main Themis cryptographic services: Secure Cell: a multi-mode cryptographic container, suitable for storing anything from encrypted files to database records and format-preserved strings.

  For the release 0.9.2 of Themis, we did a lot of minor and a few major changes:  Infrastructure: Much better documentation. Updated documentation reveals Themis Server, helpful associate for Themis library: a server where you can see current project status and try out different encryption techniques in your app with server as second party. Official tutorial will follow up soon. All platforms and languages are fully covered in tests now

We are proud to present Themis, a novel cryptographic services library. Every good work of software starts by scratching a developer's personal itch. (The Cathedral and the Bazaar) What is Themis? Themis is a high-level cryptographic services library: a library that provides easy to use, highly abstracted set of functions for solving real-world security problems. We would like you to focus on building your software with security taken care of by professionals, instead of scrupulously assembling the building blocks of cryptosystems, resolving implementations, platform availability, vulnerabilities, and performance constraints yourself.
