Get started

Important

This version of Percona Transparent Data Encryption extension is not recommended for production environments yet. We encourage you to test it and give your feedback.

This will help us improve the product and make it production-ready faster.

Release Highlights¶

The Alpha1 version of the extension introduces the following key features:

You can now rotate principal keys used for data encryption. This reduces the risk of long-term exposure to potential attacks and helps you comply with security standards such as GDPR, HIPAA, and PCI DSS.
You can now configure encryption differently for each database. For example, encrypt specific tables in some databases with different encryption keys while keeping others non-encrypted.
Keyring configuration has undergone several improvements, namely:
- You can define separate keyring configuration for each database
- You can change keyring configuration dynamically, without having to restart the server
- The keyring configuration is now stored in a catalog separately for each database, instead of a configuration file
- Avoid storing secrets in the unencrypted catalog by configuring keyring parameters to be read from external sources (file, http(s) request)

Improvements¶

Renamed the repository and Docker image from postgres-tde-ext to pg_tde. The extension name remains unchanged
Changed the Initialization Vector (IV) calculation of both the data and internal keys
