verschlüsseln vs verdeutlichen
to clarify
'verdeutlichen' and 'verschlüsseln' are opposites here. 'verdeutlichen' makes information clearer and easier to understand. 'verschlüsseln', by contrast, deliberately makes information not directly readable or hard to understand. This can be technical, for example with data, or linguistic, when someone expresses something very indirectly. In short: 'verdeutlichen' opens up the meaning, while 'verschlüsseln' protects or hides it.
