This functions performs the Tiny Encryption Algorithm on the given string and returns the base64 representation of the encrypted string.

[[{{{image}}}|link=]] Important Note: Use encodeString instead, because teaEncode inflates the file size by as high as ~77% (or by ~33% if the input isn't binary converted to base64 string).


string teaEncode ( string text , string key )

Required Arguments

  • text: The string you want to encrypt. (See second example if you want to encode binary data)
  • key: The key that should be used for encryption (Only first 16 characters are used)


Returns the base64 representation of the encrypted string if the encryption process was successfully completed, false otherwise.

This example creates a /teaencrypt command, which performs the TEA on a given string with the specified key, if any.

function encryptString( cmd, theString, theKey )
    if ( theString ) then
        if ( not theKey ) then
            theKey = string.rep( string.char( math.random( string.byte( "a" ), string.byte( "Z" ) ) ), 10 ) -- Generate a random key of 10 characters if no key was passed in as an argument
        local encodedString = teaEncode( theString, theKey ) -- Encode the string with the key
        outputChatBox( "The encoded string is: " .. tostring( encodedString ) .. " (used key: " .. theKey .. ")" )
        outputChatBox( "Syntax: /" .. cmd .. " [string] <[key]>" )
addCommandHandler( "teaencrypt", encryptString )

This shows how to use teaEncode/teaDecode with binary data:

function teaEncodeBinary( data, key )
    return teaEncode( base64Encode( data ), key )

function teaDecodeBinary( data, key )
    return base64Decode( teaDecode( data, key ) )
