From 008016b947abd2874da1eef1a7ee8d684eae6db2 Mon Sep 17 00:00:00 2001 From: Femi <114834028+Toyosi5566@users.noreply.github.com> Date: Fri, 16 Oct 2026 15:32:36 +0100 Subject: [PATCH 1/2] security: ignore local environment files .env is read by dotenv.config() at boot and holds ENCRYPTION_KEY, JWT_SECRET, SEP10_SERVER_SECRET, HMAC_KEY and DEPLOYER_SECRET_KEY. None of the .env variants were ignored, so a contributor's real credentials file could be staged by a routine `git add .` with nothing to warn anyone. Ignore the .env variants and keep the committed example file trackable. No .env file is tracked at HEAD and no .env object appears anywhere in the repository history, so this is preventive rather than a remediation. --- .gitignore | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/.gitignore b/.gitignore index bea4619..ac0c2db 100644 --- a/.gitignore +++ b/.gitignore @@ -3,3 +3,12 @@ coverage/ *.lcov coverage-final.json clover.xml + +# Local environment files. .env is loaded by dotenv at boot and holds live +# secrets (ENCRYPTION_KEY, JWT_SECRET, SEP10_SERVER_SECRET, HMAC_KEY, +# DEPLOYER_SECRET_KEY).
