From 1aeaee6ad4a8412f60052cef80417c8c7e915802 Mon Sep 17 00:00:00 2001 From: ArchieIndian Date: Mon, 16 Mar 2026 00:49:04 +0530 Subject: [PATCH] Add config-encryption-auditor skill Scans ~/.openclaw/ config files for plaintext API keys, tokens, and world-readable permissions. Suggests environment variable migration. Cron runs Sundays 9am. Companion script: audit.py with --scan, --fix-permissions, --suggest-env, --status commands. Inspired by OpenLobster's AES-GCM config encryption layer.
