Syntax

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

Required Arguments

  • algorithm: The algorithm to use.
  • input: The input to decode.
  • 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

Returns the decoded string if successful, false otherwise. If a callback was provided, the decoded string is argument to the callback.

Example

Adds an /decode command in which you can provide an algorithm, key and data to decode.

                local decoded = decodeString(algorithm, text, { key = key })
