Module NormalHashFunction

Provides default sources, sinks and sanitizers for detecting “use of a broken or weak cryptographic hashing algorithm on sensitive data” vulnerabilities on sensitive data that does NOT require computationally expensive hashing, as well as extension points for adding your own.

Also see the ComputationallyExpensiveHashFunction module.
