.decrypt_without_validating_signatures(data) ⇒ Object

this is a quick workaroundfor situations where finding a dotgpg directory is difficult.

THIS WILL NOT VERIFY THE INPUT WAS SIGNED THIS WILL NOT VERIFY THE INPUT SIGNATURE IS VALID THIS WILL NOT VERIFY THE INPUT SIGNATURE IS TRUSTED

see Dir#decrypt for the right way to read files.
