PSO2Proxy is a open source protocol proxy for the Japanese MMORPG, Phantasy Star Online 2 written in python. It allows the game's packet data to be unencrypted, logged, parsed and modified to both the client and server. It can also be used to connect to the game's servers if a client is blocked from normally connecting for any reason.
This program allows you to host your own PSO2Proxy on a server you have access to. If you just want to play the game via the proxy, a public PSO2Proxy server is available for users who can't connect to PSO2 and users who want to contribute data for packet analysis. This server can be found at pso2proxy.cyberkitsune.net. Below are the instructions for installing and setting up your own PSO2Proxy server.

PSO2Proxy uses the Twisted Framework and PyCrypto. Please install these from their respective websites or use the commands below depending on your distribution.
sudo apt-get install python-twisted python-crypto python-yaml python-faulthandler python-pip openssl git
git clone https://github.com/cyberkitsune/PSO2Proxy.git ~/PSO2Proxy
echo deb http://http.debian.net/debian wheezy-backports main|tee /etc/apt/sources.list.d/wheezy-backports.list>/dev/null
apt-get update
apt-get -t wheezy-backports install python-twisted
sudo yum install python-pip gcc python-devel git
git clone https://github.com/cyberkitsune/PSO2Proxy.git ~/PSO2Proxy
cd ~/PSO2Proxy
sudo pip install -r requirements.txt
git clone https://github.com/cyberkitsune/PSO2Proxy.git ~/PSO2Proxy
cd ~/PSO2Proxy
pip install -r requirements.txt
cd ~/PSO2Proxy/proxy
python ./PSO2Proxy.py
To configure the server, run it once to generate the pso2proxy.config.yml in ~/PSO2Proxy/proxy/cfg/
, then edit that. You need to at least set your Public IP address in myIpAddr
, and your adapter IP if it is different from your public IP. If unsure, leave the bindIp
as 0.0.0.0
.
You'll need to generate an RSA public and private keypair for your server and your proxy's clients for the proxy to work. You can use OpenSSL to do this.
First, change into the keys folder.
cd ~/PSO2Proxy/proxy/keys
Generate the private key:
openssl genpkey -out myKey.pem -algorithm rsa -pkeyopt rsa_keygen_bits:1024
Generate a compatible publickey.blob for your clients:
openssl rsa -in myKey.pem -outform MS\ PUBLICKEYBLOB -pubout -out publickey.blob
You'll ALSO need to import SEGA's RSA public keys from the PSO2 client. For instructions on how to get SEGAKey.blob, see this wiki page.
To convert SEGAKey.blob to SEGAKey.pem, use this OpenSSL command:
openssl rsa -pubin -inform MS\ PUBLICKEYBLOB -in SEGAKey.blob -outform PEM -out SEGAKey.pem
You'll need to set your system's locale to UFT8 instead of ASCII, so it can properly parse JP characters.
On Debian systems, you can use this command:
dpkg-reconfigure locales
Make sure to uncheck everything but en_US.UTF-8
, and reboot your machine after the process is completed.
PSO2Proxy has several plugins that come bundled in to make the experience better. Most of them are disabed by default, with the exception of LoginMessage
and GlobalChat
. To disable a plugin that is not in the disabled folder, simply delete it.
If you would like to enable a plugin already in the disabled folder, use the following command to make symlinks so they get updated.
cd ~/PSO2Proxy/proxy/plugins
ln -s disabled/DisabledPluginName.py .
Note that some plugins may have additional steps involved to get them working. If you have issues, you should check for a new config file in ~/PSO2Proxy/proxy/cfg
, consult the Wiki, or contact us on IRC.
For automatic configuration using PSO2Tweaker, simply enable WebAPI.py and point the tweaker to http://your.ip.addr.here:8080/config.json
To enable WebAPI...
cd ~/PSO2Proxy/proxy/plugins
ln -s disabled/WebAPI.py .
Be sure that publickey.blob
is in your keys/
folder.
To get clients to connect to your proxy, they need to think SEGA's servers are your servers. An easy way to do this is to modify Windows's hosts file, add the following code below to the hosts file in c:\Windows\System32\Drivers\etc\hosts
, replacing 0.0.0.0 with the proxy's IP address.

To get the proxy to decrypt the client's packets, place the publickey.blob you generated in the same folder as PSO2.exe, and rename the RSAKeyInjector.dll to ddraw.dll in that same folder. If you use PSO2Tweaker to launch PSO2, enable the item translation patch and rename ddraw.dll to rsainject.dll instead.
