Shadowsocks Config and QR Code

Config File

QR Code is encode from ss.json, config of shadowsocks looks like:

{
    "server": "my_server_ip",
    "server_port": 8388,
    "local_port": 1080,
    "password": "barfoo!",
    "timeout": 600,
    "method": "table"
}

Explanation of each field:

server: your hostname or server IP (IPv4/IPv6).
server_port: server port number.
local_port: local port number.
password: a password used to encrypt transfer.
timeout: connections timeout in seconds.
method: encryption method, “bf-cfb”, “aes-256-cfb”, “des-cfb”, “rc4”, etc. Default is table, which is not secure. “aes-256-cfb” is recommended.

URI and QR code

Shadowsocks for Android / iOS also accepts BASE64 encoded URI format configs:

ss://BASE64-ENCODED-STRING-WITHOUT-PADDING

Where the plain URI should be:

ss://method:password@hostname:port

For example, we have a server at 192.168.100.1:8888 using bf-cfb encryption method and password test. Then, with the plain URI ss://bf-cfb:test@192.168.100.1:8888, we can generate the BASE64encoded URI:

ss://YmYtY2ZiOnRlc3RAMTkyLjE20C4xMDAuMTo40Dg4

This URI can also be encoded to QR code. Then, just scan it with your Android/iOS devices

Decode QR Code

1. Use any QR Code scanner decode the QR Code into URI like
   `ss://encode_string`

2. Use `echo encode_string | base64 --decode` to decode the URI

3. Done!
