JAVA.CRYPTO.WHAF : Weak Hash Algorithm Field (Java)

Summary

A weak, possibly reversible cryptographic hash algorithm is used.

Some cryptography algorithms are nowadays considered as outdated and unsafe or actually broken, since they are too easy to decode.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.

The OWASP documentation provides more information on Using the Java Cryptographic Extensions.
