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.

Convention: Byte array notation as it would appear in a hexeditor.

= Layout=

KDBX files, the keepass database files, are layout as follows:

1) Bytes 0-3: Primary identifier, common across all kdbx versions: 
  private static $sigByte1=[0x03,0xD9,0xA2,0x9A];

2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1)
