SFAIK under all circumstances. The workaround (if memory serves) is to store 
base64Encode(compress(tData)) in a userProperty instead, but there is no space 
saving. Has been a 'feature' since mc.forever and therefore .rev also as the 
underlying code.

MCEncrypt is internal use only and is, I believe, the engine used when a 
stack is password protected. So yes.
