This function encodes a string using the specified algorithm. The counterpart of this function is decodeString.

Syntax

string encodeString ( string algorithm, string input, table options [, function callback ] )

Required Arguments

  • algorithm: The algorithm to use.
  • input: The input to encode.
  • options: A table with options and other neccessary data for the algorithm, as detailed below.

Options for each algorithm

Optional Arguments

  • callback: providing a callback will run this function asynchronously, the arguments to the callback are the same as the returned values below.

Returns for each algorithm

  • tea
    • encodedString: the encoded string if successful, false otherwise. If a callback was provided, true is returned immediately, and the encoded string is passed as an argument to the callback.
  • aes128
    • encodedString: the encoded string if successful, false otherwise. If a callback was provided, true is returned immediately, and the encoded string is passed as an argument to the callback.
    • iv: (Initialization vector) this is a string generated by the encryption algorithm that is needed to decrypt the message by DecodeString. If a callback was provided, true is returned immediately, and the iv is passed as an argument to the callback.

Example

Adds an /encode command in which you can provide an algorithm, key and data to encode. Below is the example provided as both server-side and client-side variations.

Server
addCommandHandler("encode", 
    function(player, _, algorithm, key, ...)
        if algorithm and key then
            local text = table.concat({...}, " ")
            if type(text) == "string" and text ~= "" then
                local encoded = encodeString(algorithm, text, { key = key })
                if encoded then
                    outputChatBox("The result of " .. algorithm .. " encoding is: " .. encoded, player)
                else
                    outputChatBox("Failed to encode. Make sure that all arguments are valid.", player, 255, 0, 0)
                end
            else
                outputChatBox("Please specify text in the command.", player, 255, 0, 0)
            end
        else
            outputChatBox("Invalid algorithm and/or key.", player, 255, 0, 0)
        end
    end
)
