Module WeakSensitiveDataHashingQuery

Provides a taint-tracking configuration for detecting use of a broken or weak cryptographic hashing algorithm on sensitive data.

Note, for performance reasons: only import this file if WeakSensitiveDataHashing::Configuration is needed, otherwise WeakSensitiveDataHashingCustomizations should be imported instead.

Import path

import semmle.python.security.dataflow.WeakSensitiveDataHashingQuery

Predicates

computationallyExpensiveHashFunctionFlowPath	Holds if data can flow from `source` to `sink` with `ComputationallyExpensiveHashFunction::Flow`.
normalHashFunctionFlowPath	Holds if data can flow from `source` to `sink` with `NormalHashFunction::Flow`.

Modules

ComputationallyExpensiveHashFunction	Provides a taint-tracking configuration for detecting use of a broken or weak cryptographic hashing algorithm on passwords.
NormalHashFunction	Provides a taint-tracking configuration for detecting use of a broken or weak cryptographic hash function on sensitive data, that does NOT require a computationally expensive hash function.
