• Sniffing Creds with Go, A Journey with libpcap

  In the good ol’ days to write a credential sniffer you had to spend alot of time learning C and libpcap this was extremely time consuming and no one really wants to go through that. So today we have GoLang, the statically typed language from google, specifically the gopacket library from google. Gopacket is a library that introduces packet filtering and capturing to go. It comes with C Bindings for libpcap, C Bindings for pfring, afpacket C Bindings and tcpassembly.

• XML To JSON in Golang Demystified

  There comes a point in every developer’s life where XML data is painfully unavoidable to work with. RSS Feeds try to make this easier but everyone prefers good ol’ JSON, unless you are a sadist. In Golang we can attack this in a number of ways like using an XML to JSON Library, but why not use the Go standard libraries and save some vendoring issues. Building our own XML to JSON function I was recently working on something that required a Medium RSS feed published to a website and thought why not use a GoLang function running on OpenFaaS to accomplish this.

• Building a ToDo API with Golang and Kubernetes! – Part 3 – Building and Deploying our Application

  In [Part 1][1] and [Part 2][2] we built a functional API using Golang and MongoDB, although as it stands its insecure. We can add password protection using Basic Auth while deploying ([See here][3]). In this tutorial we will build a very tiny docker container and deploy to our Kubernetes Cluster. For the purposes of this tutorial I won’t be showing you how to setup a Kubernetes Cluster, However you can do it easily with [Terraform][4] and [DigitalOcean][5].
