Cryptographic values need unpredictability. Randomness used for animation or game logic may be unsuitable.
Evaluation approach
Use platform cryptographic APIs. Never ship fixed seeds introduced for testing keys, challenges or tokens.
Application example
Keep deterministic test providers separate and verify selection of the real secure provider in release builds.
Limits and considerations
Complicated-looking output does not establish cryptographic quality.
Can test values reach production?
Make deterministic providers explicit test dependencies. Check release artifacts for fixed keys and challenges; appearance is not evidence of secure randomness.
Checks and decisions
- Use platform APIs
- Separate test providers
- Scan for fixed values
