I'm a hacker, pretty much in the old school sense of the word. But I do know IT security too.

      It’s been twenty years and programmer continue to make mistakes more egregious than these early days blazing the trail of consumer-use encryption. Is there an “OWASP Top 10” for cryptographic implementation errors? @CiPHPerCoder @mattblaze @matthew_d_greenhttps://twitter.com/todayininfosec/status/1041903888427696128 …

      1995: Ian Goldberg and David Wagner shared research describing major weaknesses in Netscape Navigator 1.1's method of generating a unique seed used to generate the unique SSL encryption key and several attack techniques. The seed was based only on the pid, ppid, and time. pic.twitter.com/kbFqqSY89u

      All that said, infosec in general & respected open source contributors like Google seem blind to threat of unsigned JavaScript. Last week BA users had their creds stolen via 22 lines of TLS 1.2 or 1.3 encrypted Javascripthttps://www.riskiq.com/blog/labs/magecart-british-airways-breach/ …

      Secure code delivery is a particular hobby horse of mine, and I've been trying to make signed code the norm in the PHP ecosystem:https://github.com/composer/packagist/issues/797 …

      Whoa. Now you're talking! That's awesome! Great job. I'm no dev, but I stood-up my own PKI and digitally sign all my powershell scripts. Real security involves more than just encryption. It involves authentication. Our .exes and other execution engines need signatures to help

      I've outlined, loosely, the sort of PKI I'd like to implement for this sort of project here:https://github.com/paragonie-scott/public-projects/issues/5 …

      While I read through this, let me ask you this: you're rolling your own crypto are you not? There are four principles in secure messaging, and most people say all are answered by x509 PKI. We use digital signatures based on x509 daily https://tools.ietf.org/html/rfc5280

      I also wrote https://github.com/paragonie/sodium_compat …. I'm very familiar with how cryptographic systems fail. My write-up for sodium_compat's design is here: https://paragonie.com/blog/2017/02/cryptographically-secure-php-development …

      Generally speaking: X.509 is a swiss army knife. Complexity is one of the enemies of security. For example: basic constraints. https://www.blackhat.com/presentations/bh-dc-09/Marlinspike/BlackHat-DC-09-Marlinspike-Defeating-SSL.pdf …

      Swiss Army Knives feel insulted. They are elegant tools, not committee design monstrosities.
