Seth Vargo, the Director of Technical Advocacy at HashiCorp, joined the show to talk about managing secrets with their open source product called Vault which lets you centrally secure, store, and tightly control access to secrets across distributed infrastructure and applications. We talked about Seth's back story into open source, use cases, what problem it solves, key features like Data Encryption, why they choose to write it in Go, and how they build tooling around the open core model.
