      "We have both internal and external review of our code to ensure that it is secure" I'd focus on its failure rather than OSS or not

      I understand reasons for not going OSS, however I don't like poor claims and incorrect justifications (https://www.yubico.com/2016/05/secure-hardware-vs-open-source/ …)...

      Which were the poor claims? Easier if you point to specifics in the article (it's quite long).

      too many for tweets, re first one I find it indelicate to point that a bug was found not because of OSS and use it as justification

      when that specific bug was a clear sign of the vendor not auditing their code...at all, because that bug was so easy to find...

      Exactly. So instead of opening YK4 source, @Yubico should make transparent their _security practices_.

      Had they been clear about Neo applet being untested 3rd party code then we would have known it couldn't be trusted.

      But opening all of their code does nothing to help us decide if it's good or not. Only verification can do that.

      I disagree, it helps and it doesn' hurt...it might contribute 0 worst case but certainly it doesn't hurt technical interests

      I am just disappointed with the slow migration to a different model based on commercial concerns rather than technical

      and the apparent mismanagement of at least 2 security bugs in my mind, again I find the all != OSS dissertation as indelicate

          I am not against OSS. I just don't want people to assume OSS == more secure. Assurance can be built without opening source.

          yes, I disagree on the opposite "There is an inverse relationship between making a chip open and achieving security certifications"

          that is a quote from the post, their initial OSS use is being reversed, somwehat criticized and it was poorly managed to begin with

          Not really a reversal. No yubikey source has ever been open AFAIK. The applet loaded on Neo was badly managed 3rd party OSS.

          incorrect, they took ownership of their fork https://github.com/Yubico/ykneo-openpgp …

          They forked an OSS project and kept their fork open. PGPCard functionality in YK4 is unrelated code. Clearly stated in blog.

          Just because a new product has same function as old one doesn't mean you have a moral obligation to open source code.
