This is a study repository. Security considerations apply to the code examples and scripts.

• Azure API keys or subscription keys
• Azure subscription IDs or tenant IDs
• Connection strings with credentials
• .env files with real values

All secrets should be stored as environment variables. See src/python/env-template.txt.

If you find a real security vulnerability in the example code (e.g., command injection, credential exposure), please open a GitHub Issue marked [SECURITY].

All code in this repository uses DefaultAzureCredential() from azure-identity. This is the exam-recommended pattern and does NOT require API keys in code.

from azure.identity import DefaultAzureCredential
credential = DefaultAzureCredential()
