In 2012 I released a DES cracking service with Moxie Marlinspike for cracking MSCHAPv2 and quickly started seeing it being used for cracking other things besides MSCHAPv2. In this presentation we’ll take a look at some of the research I’ve done into other widely used protocols and services that still rely on DES for security and provide an quick intro into the https://crack.sh API so you too can use this service for your own projects.
