The very large boast from https://danodowd.com tells me he is either a joke or detached from modern security:

     I designed and wrote the core security system for our nuclear forces, military and commercial aircraft, Top Secret encryptors, laptops for FBI field agents, and military cellphones and radios. This software has been certified by the NSA to Common Criteria EAL6+, a higher level of security certification than achieved by any other software. Has your security “expert” ever designed and written the security software for a system that never fails and can’t be hacked? Or, do they claim that no one can write software that never fails and can’t be hacked? I do it every day.
