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 )

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

Returns

Returns the encoded string if successful, false otherwise.

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.
