What is this

ddlcpad is short of Doki Doki Literature Club Plus Asset Decrypter

You can decrypt the *.cy file from Doki Doki Literature Club Plus with this cli binary.

After decrypt, you will get a *.out file. Put it into Perfare/AssetStudio to get the assert file.

How to install

You can download a binary file on release. Or you can build it yourself.

How to use

Just open your terminal (or powershell on windows), run the binary file.

Basic usage:

# On Linux
./ddlcpad <file_name>
# On windows
.\ddlcpad.exe <file_name>

Use --help or -h to get more help.

How to build

Just install and config golang on your computer, then run this command:

# On windows
go build -o ddlcpad.exe
# On Linux
go build -o ddlcpad

If you wants to build exe file on Linux:

export GOARCH=amd64
export GOOS=windows
go build -o ddlcpad.exe

Why do this

There has a project do this. But I don't use php and don't want to install it on my computer. Actually, I don't know how to setup and use the php code. And also lazy to learn it.

What's more, php script for those who doesn't lean programming are very very hard to use. I wants to create a binary file which is easy to use. So that people can just download a binary file from release and use it without build or run code themselves.

Why read file with ioutil.ReadFile()

The biggest assert file is gallery_images.cy and with 582 MB, There is no way to use too much memory.

PR welcome. :)
