Procedure
Ask for the old and new API keys if not provided
Identify all target files — .env files, keystore files (
keys.json), and logs containing credentials:find {{SEARCH_PATH}} -name "*.env" -o -name "keys.json" -o -name "*.log"Create backups and replace the key in each file:
sed -i.bak "s|{{OLD_KEY}}|{{NEW_KEY}}|g" {{FILE_PATH}}Verify the replacement in a sample of updated files:
grep -o "sk-[a-zA-Z0-9-]*" {{FILE_PATH}} | head -1Report a summary of all updated files, backup locations, and verification results
Notes
- Backups are created automatically using the
-i.bakflag before any changes - Verify replacements before confirming completion
- Revoke the old key in the API provider's dashboard after rotation
- Large log files may take time to process
