AWS Advanced JDBC Wrapper now provides client-side encryption

The AWS Advanced JDBC Wrapper now provides column-level client-side encryption through its KMS Encryption plugin. The wrapper provides advanced capabilities such as failover handling, AWS authentication integration, and enhanced monitoring for Amazon Aurora and Amazon RDS open source databases. It enables Java applications to encrypt sensitive data before it reaches the database without changing application code.

Database encryption at rest and TLS in transit are foundational security controls. However, with these controls decrypt the data within the database engine. A compromised credential, overprivileged administrator, or SQL injection attack can expose sensitive data in plaintext, creating compliance risk under PCI DSS, HIPAA, and GDPR. The KMS Encryption plugin closes this gap by working at the JDBC driver level. When your application writes to an encrypted column, the plugin encrypts the value before it reaches the database. When reading, it decrypts the value before returning it. Plaintext remains visible only to your application, while the database sees encrypted values. The database can verify data integrity through HMAC validation without needing the encryption key. The plugin integrates seamlessly with your existing SQL, Spring, Hibernate, and connection pool setup without requiring code changes.

The KMS Encryption plugin works with Amazon RDS and Amazon Aurora PostgreSQL and MySQL-compatible databases.

The plugin is available as an open-source project under the Apache 2.0 license. To learn more, see AWS Advanced JDBC Wrapper documentation.
