##Want to write your own template?

#Variables At the moment the engine support the following keyword var, func, data, cond, int

The engine also support following variables [int], [smallint].

This mean that everytime one of these keyword is found it will be replace with random value.

Function func1(var1 As String) As String
  Dim var2 As String
  Dim int1 As Integer
  int1 = [smallint1]
  If (var2 = var1) Then
    func1 = "cond1"
  End If
End Function

Will become

Function groJeU(JToaRdHxMcE0 As String) As String
  Dim CoVSEHgccgKzTV0 As String
	Dim BsviMcpRUPErzxVJ As Integer
	BsviMcpRUPErzxVJ = 4
	If (CoVSEHgccgKzTV0 = JToaRdHxMcE0) Then
	  groJeU = "mrkOOiQriGHJrABNJXf"
	End If
End Function

#Parsing instructions To tell the parser to encode a string use the following pattern {[your data]}. The string will be encoded using the offset defined by encodingoffset in the JSON config file.

If you are using keyword that are not supported by the parser add the following line [use:varname] at the beginning of your VBA code.

Keep in mind that encoded string need to be decoded. There is a VBA function for that simply add encoderinto the evasion array to include the decode function. Since the [use:decode] is already defined inside of encoder.vba the decode function will be obfuscated as expected.

#User defined variables Want to add specific variable like a URL. Simply define it in the template like this [URL]

[use:myfunction]

Function myfunction(var1 As String) As String
  Dim var2 As String
  Dim int1 As String
  int1 = [smallint1]
  var2 = decode("[URL]")
  If (var2 = var1) Then
    myfunction = "cond1"
  End If
End Function

Once it will be parsed by the Python script the variable will be replace by the value defined in the config file
