zCrypt::encrypt	(	$	str,
		$	base64 = false
	)

Encrypts a String / Array according to the settings.

on encryption decryption on your Control Panel . If array given returns ther encrypted array else returns the encrypted array. If integer or float given Converts it to string and then encrypts it. if second argument(boolian true / false(By default)) is applied (as true) base64_encode on the encrypted text before returning. Remember that Output would be Same always if the Same source String is Supplied and Settings are same. as it Stores the IV(Initialization vector) in its settings file and use that Stored IV if any mode other than ecb is used (NOE : To use Dynamacally generated IV use denc(), menc(), or tenc() )

Parameters:

	$str	mixed
	$base64	boolean

Returns:

mixed
