Shadowsocks Android and iOS supports QR Code configuration.

Update: now you can also scan QR code on Windows, Linux, and OS X.

Protocol

You can encode your server configuration to a QR Code.

1. Put your configuration together like this:

    method:password@hostname:port
   

2. Transform it into base64:

    bWV0aG9kOnBhc3N3b3JkQGhvc3RuYW1lOnBvcnQ=
   

3. Prepend with ss://

    ss://bWV0aG9kOnBhc3N3b3JkQGhvc3RuYW1lOnBvcnQ=
   

4. Generate a QR Code from the url above.

Generate via GUI clients

You can also generate QR Codes from some GUI clients:

• Shadowsocks for Windows
• Shadowsocks for OS X
• Shadowsocks-Qt5
• Shadowsocks GUI

Generate via Command line

pip install qrcode
echo -n "ss://"`echo -n aes-256-cfb:password@1.2.3.4:8388 | base64` | qr

If you can't scan the code, try changing your terminal font.
