Keepass file format explained

I’m currently working (I’m just at the beginning, and I’m quite slow) on a personal project that will use Keepass files (kdb and kdbx).
I tried to find some documentation about .kdb and .kdbx format, but I didn’t find anything, even in the Keepass official website. I you want to know how these file formats are structured, you must read Keepass’s source code. So I wrote this article that explains how Keepass file format are structured, maybe it will help someone.

We've created a Bloc Mentor Slack Group. If you want to be added, just send me your email. Either respond directly to this or email me at RRP54@cornell.edu.

Introductory Message

Hi teammates,

My name is Ricky. I'm a fellow Rails and iOS Mentor residing in NYC.

It's time! It's time to have our own mentor Slack Group. Students across curriculums have already been using their own Slack Groups to seek help from fellow students, and it's been proving extremely helpful. I'm sure it would do the same for us mentors.
