As the days were getting shorter, our pull requests were getting longer, and here we are now, proud to present Acra 0.83.0. Its distinctive new feature is the AcraRotate utility, which allows you easily rotate the storage keys on a regular basis or perform an emergency key rotation if you’ve detected (or suspect) a compromise of the client app.
SQL filtering got more flexible — the new 6 patterns (including SUBQUERY and LIST_OF_VALUES) allow deep customisation for configuring the accepted queries and blocking malicious requests.
Starting with Acra 0.83.0, all of the current documentation for Acra can only be found on the Cossack Labs Documentation server (you can also find the documentation for our other product, i.e. Themis and Hermes).
One of the easiest ways to try Acra is to deploy it with Docker However if you don’t wish to install a thing, but still want to experience the full might of Acra, we are proud to present the Acra Live Demo — a web-based demo of a typical web-infrastructure protected by Acra and deployed on our servers for your convenience. Encrypt data from a Python application, store it in a PostgreSQL database, decrypt data through Acra – in just one click. Try to run malicious SQL queries and watch how they are blocked by AcraCensor.
