Technology Prototyping and Evangelism

Sunshine PHP

| Comments

Last week I had a chance to speak at Sunshine PHP about Identity and Data Security in PHP. This was a dive into the fundamentals of protecting user identity through password security, and diving into different ways to protect data as it’s being transmitted, both through secure and insecure channels.

Within the talk, I cover several topics in the space:

  • Password Security (attack vectors, salting / peppering, hashing methods).
  • Ideal data security (SSL/TLS and how to set up your own self-signed certificate).
  • Insecure channel security using Symmetric cryptography (shared secret key) and Asymmetric cryptography (public / private keys).

The screencast of the session is available below:

More information on this subject can be found in our upcoming book, Identity and Data Security for Web Development.

Hi all,

Rebuilding Commerce

Earlier last month, I was giving a keynote down in Sao Paulo, Brazil at Campus Party. The topic I covered was a new way of looking at financial technology for me, and explored the inadequacies of current banking and financial institions. I dove into some of the reasons why over 50% of the worlds population are unbanked (having no bank account), and how technology is quickly leaving these people behind. That market struggles, as technology is not geared towards them, but it’s one that is ripe for complete disruption.

Many of the reasons why I care about this industry are from some personal hardships early in my professional life, which I go through in the talk.

The video clip is available below:

Also, the core slides from my talk are here:
