From 751c09c192fd030ccd25e54b7b1f8f539f6bbe1a Mon Sep 17 00:00:00 2001 From: Dave Cramer Date: Mon, 22 Sep 2025 15:50:00 -0400 Subject: [PATCH 1/7] initial commit of encryption plugin working code updated packages and added license files moved to correct package and now compiles recovered the parser code fix javadoc warnings removed reflection and added test for SqlAnalysisService add AwsWrapperProperty to EncryptionConfig cleaned up the configuration properties and added docs working code update SQLAnalyzer to handle more complex joins refactored to use jooq parser instead of our own PostgreSQL parser refactored to use jooq parser instead of our own PostgreSQL parser removed jooq and used JSQLParser removed unused methods fixed documentation ---
