AWS adds post-quantum key exchange to Aurora PostgreSQL

Published Thursday, October 29, 2026 · 6:06 PM EDT

AWS says Amazon Aurora PostgreSQL-Compatible Edition now supports post-quantum TLS key exchange, adding a cryptographic option for protecting database data in transit. Aurora PostgreSQL versions 18 and higher let administrators modify the ssl_groups parameter to select cryptographic groups from an AWS allow list. That gives organizations a way to configure key exchange to match their security standards. The new configuration support applies to versions 18 and higher.
