I mean "pervasive encryption" - datasets encrypted using z/OS facilities.
Usually one can check whether dataset is encrypted by using ISPF/PDF
Info or LISTCAT.
However when a dataset is accessed "from outside" - i.e. via shared
DASD, the result of open attempt is usually an abend x13.
There are some exceptions, rather low-level like print track. Obviously
the content is unreadable.
Now the question: is there any eye catcher or signature which allow to
recognize it is actually encrypted file, not just bunch of random bytes?
