Acra has client libraries for Ruby, Python, Go, C++, NodeJS, PHP, iOS (Objective-C and Swift) and Android, but you can easily generate AcraStruct containers with Themis for any platform you want.
Acra currently supports PostgreSQL 9.4-11 and MySQL 5.7+, and their flavours like MariaDB. KV and NoSQL databases (like MongoDB) have limited support (via AcraTranslator; some features like SQL firewall are not supported).
Acra is a database encryption proxy for data-driven apps: strong selective encryption, SQL injections prevention, intrusion detection, honeypots.
Acra helps you protect data in web and mobile applications with centralised data storage.
