Description
Removes weak hash algorithms such as MD5 and SHA1 from
java/weak-cryptographic-algorithmand adds these cases tojava/potentially-weak-cryptographic-algorithminstead.The removal of weak hash algorithms from
java/weak-cryptographic-algorithmaligns with other languages, e.g. #11129.Consideration
Let me know if there is any concern with changing the behavior of
rankedInsecureAlgorithminstead of doing the exclusion forjava/weak-cryptographic-algorithmdirectly in BrokenAlgoLiteral? I chose to do the exclusion inrankedInsecureAlgorithmsince doing so automatically adds the weak hash cases tojava/potentially-weak-cryptographic-algorithmdue to this code.Note that there were some overlapping results between the two queries for cases where a weak hash algorithm string literal is used as the default value in a
getPropertycall (e.g. the "MD5" value in this test case). In order to avoid duplicate results for these cases in thejava/potentially-weak-cryptographic-algorithmquery, I've added an exclusion toInsecureAlgoLiteral.
