I like having my SSH commit signing automatically configured. In a previous article, I discussed how you can do this using your dotfiles repository. If you want to add support for reading the SSH keys from 1Password, then there are just a few more things you need to know.

With automation you can simplify many things as a developer. This includes automating the process of configuring commit signing with dotfiles.

What you don’t know can hurt you, especially when it comes to code. Dependency chains can tend to have more security considerations than most people realize. In fact, most dependencies have far more abilities than most developers realize …

For certificates to work, we need a system of trust. We need to know that each certificate is valid and was properly issued. This is the role of the certificate authorities (CAs). In the second part of this series, we’ll explore the role of CAs and how certificates are validated. We’ll also look at creating a private CA using a self-signed certificate.

Despite decades of use, certificates tend to be a mystery to most developers. At their root, they are largely more than a collection of name-value pairs and a public key. The majority of people that work with certificates regularly often run into situations where they need to understand the details of how they work. In this post, we’ll dive into the basics and learn what’s in these files.
