Package com.h3xstream.findsecbugs.crypto

Class CipherWithNoIntegrityDetector

  • All Implemented Interfaces:
    edu.umd.cs.findbugs.Detector, edu.umd.cs.findbugs.Priorities, org.apache.bcel.classfile.Visitor
    public class CipherWithNoIntegrityDetector
extends edu.umd.cs.findbugs.bcel.OpcodeStackDetector
    This detector mark cipher usage that doesn't provide integrity.

    The identification will be made base on the mode use.

    Bad modes:
    • ECB
    • CBC
    • OFB
    • ...
    Safe modes:
    • CCM
    • CWC
    • OCB
    • EAX
    • GCM
