pg_tde release notes

Alpha 1 (2024-03-28)

pg_tde extension brings in Transparent Data Encryption (TDE) to PostgreSQL and enables you to keep sensitive data safe and secure.

Get started

Release Highlights

The technical preview of the extension introduces the following key features:

  • You can now rotate master 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

Bugs fixed

  • Fixed toast related crashes
  • Fixed a crash with the DELETE statement
  • Fixed performance-related issues
  • Fixed a bug where pg_tde sent many 404 requests to the Vault server
  • Fixed сompatibility issues with old OpenSSL versions
  • Fixed сompatibility with old Curl versions

MVP (2023-12-12)

The Minimum Viable Product (MVP) version introduces the following functionality:

  • Encryption of heap tables, including TOAST
  • Encryption keys are stored either in Hashicorp Vault server or in local keyring file (for development)
  • The key storage is configurable via separate JSON configuration files
  • Replication support
