Setup WebDAV as a source for Mayan EDMS

I have recently switched to a Document Management System (DMS) to organize my documents. A deeply nested folder structure on my Nextcloud wasn’t an option anymore, I wanted a system with full-text search. I quickly settled on Mayan EDMS, probably the most popular open-source DMS and easily deployable with docker. Let’s run a quick test, I thought: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 version:"3.

Securing a go REST API - Part 4: CSRF

This is part 4 of a multipart series on how to secure your API in golang. This post will talk about dealing with Cross-Site Request Forgery (CSRF in short), an attack on web applications where the attacker tricks users into performing unintended actions. This attack only works for APIs served to a frontend (e.g. a React application), as it is based on the fact that browsers send the user’s cookies automatically when calling a web page.

Securing a go REST API - Part 3: Passwords, Tokens and Secrets

This is part 3 of a multipart series on how to secure your API in golang. This post will talk about dealing with passwords, tokens and generally secrets.

Hash your passwords This post is not going into the details of why you should hash your passwords, but you need to look for mostly two things:

Securing a go REST API - Part 2: Timeouts

This is part 2 of a multipart series on how to secure your API in golang. We covered session management in part 1. Filippo Valsorda makes an excellent case about exposing your go service. This blogpost will only talk about one little piece of all this, namely timeouts. Timeouts are one of the rare cases where the default values aren’t secure in golang. This is mostly due to historical reasons and maintaining backwards compatibility, however the often used helper methods http.

Securing a go REST API - Part 1: Sessions

This is part 1 of a multipart series on how to secure your API in golang. This series is inspired by this blogpost where they use a token to implement stateless session management. In this part I want to talk about session management in general. More and more people recommend JWTs (JSON Web Tokens) for session management in web apps. People see different benefits for using them in session management.
