CSHARP.CRYPTO.CAWH : Cryptographic Algorithm with Weak Hash (C#)

Summary

A cryptographic algorithm that contains a possibly reversible hashing algorithm.

Some cryptography algorithms are nowadays considered as outdated and unsafe or actually broken, since they are too easy to decode. This checker identifies uses of unsafe algorithms for cryptography.

Properties

Class Name Cryptographic Algorithm with Weak Hash (C#)
Significance security
Mnemonic CSHARP.CRYPTO.CAWH
Categories
CWE CWE:328 Use of Weak Hash
OWASP-2017 OWASP-2017:A2 Broken authentication
