Description: The onboarding module uses Python's hashlib.sha256() to hash credentials or API keys at line 168. SHA-256 is a general-purpose cryptographic hash function designed for speed — it is not suitable for password or credential storage. Without per-entry salting, identical credentials produce identical hashes, enabling rainbow table lookups. Without key-stretching (iterative hashing), modern GPUs can compute billions of SHA-256 hashes per second, making offline brute-force attacks trivially fast. This pattern is confirmed in both production code and tests.
