pg_vault_tde provides Transparent Data Encryption for PostgreSQL 17 and 18. A table access method, encrypted_heap, encrypts every tuple with AES-256-GCM before it reaches the storage manager and decrypts it after it leaves, so applications require no changes.
Keys are held outside the database: HashiCorp Vault or OpenBao through the Transit engine, a PKCS#11 token or HSM, or a local PKCS#12 wallet. Data encryption keys are per table and can be rotated online. Requirements are PostgreSQL 17 or 18, OpenSSL 3.x, and the library listed in shared_preload_libraries.
The current release is 1.7.1. It corrects the AAD derivation for out-of-line TOAST values, with the consequence that TOAST data written by 1.7.0 or earlier does not authenticate under 1.7.1: affected tables must be exported before the new binary is installed. The procedure is documented in the README.
pg_vault_tde is released under the PostgreSQL licence. Sources, documentation and binary .deb and .rpm packages are on GitHub; the distribution is on PGXN.
