Description:

If you encounter the following error, the issue is pcaprub uses a hardcoded path for Winpcap.  I downloaded winpcap v4.1.3 and downloaded the dev kit for Winpcap and put it in c:\WpdPack.   Additionally, since I use an x64 machine I had to copy the file C:\WpdPack\Lib\x64\*.lib into C:\WpdPack\Lib and then the compilation worked.You need pcaprub for things like msf.C:\dev\kit gem install pcaprubTemporarily enhancing PATH for MSYS/MINGW...Building native extensions.

C:/Ruby24-x64/lib/ruby/gems/2.4.0/extensions/x64-mingw32/2.4.0/pcaprub-0.13.0/gem_make.out On April 15, 2015 the PCI SSC released the PCI DSS v3.1.  The main cause for concern for most merchants and other entities (called entities hereonforth) that store, transmit and process cardholder data is the prohibition of using SSL and Early TLS .  The PCI SSC also released a supplement to assist entities in mitigating the issue.   The supplement references the NIST guideline SP800-52 rev1 for determining which are good ciphers and which are not.The key point being what does Early TLS mean?  Does it mean TLSv1.0 and TLSv1.1 OR does it mean only TLSv1.0?  Are the entities supposed to disable all ciphers except anything that s TLSv1.2?Answer is (in consultant speak) it depends .
