# gog hashdb

## What is it?

GOG's hashdb is a very simple format providing checksums for each file from given product depot

`goggame-GameId.hashdb`

## Structure

hashdb is a zip file with one entry (called the same as archive)

### Header

File starts with 3, 4-byte intigers. First two are always `12` and `1`

The third intiger is number of records

### File record

Each record is a `1024` byte file path relative to install directory.  

And `32` bytes of MD5 checksum.
