the key package. If you provide an incorrect password, you will still be able to
import the keys in the package, but you will not be able to use them to decrypt any
data that was previously encrypted using those keys.
6. From the Select Keys to Import list, select the keys that you want to import.
You can select only those keys that have a green dot and the phrase Ready for
Import
in the Status column. A red dot and the phrase Duplicate Key Name
indicates that a key of the same name already exists in this instance of VTL and
cannot be imported.
If you selected a key and subsequently decide not to import it, you can clear the key.
You can also clear all selected keys by clicking De-Select All. (You can click this
button only if the Show All Keys check box is cleared.)
Note: A key of the same name might not necessarily have the same secret phrase.
For example, you might have a key named Key1 with a secret phrase of
ThisIsTheSecretPhraseForKey1. If the key package was created by another instance
of VTL, it might also have a key named Key1, but its secret phrase might be
ThisIsADifferentSecretPhrase. Since the key names are the same, you will not be able
to import the key in the key package unless you rename the existing Key1. After you
rename the key, you can continue to use it to decrypt tapes that were encrypted
using that key, and you can also import the key named Key1 from the key package
and use it to decrypt tapes that were encrypted using that key.
7. Click OK.
The imported keys appear in the Key Name list on the Key Management dialog
box. When you subsequently export or import a tape, these key names also appear in
the Select a Key list.
Stop here.
▼ Shredding a virtual tape
Just as deleting a file from your hard drive does not completely destroy the file,
deleting a virtual tape does not completely destroy the data on the tape. If you want
to ensure that the data is unrecoverable, you must shred the tape.
Shredding a virtual tape destroys all data on the tape, making it impossible to
recover the data. Tape shredding uses a military standard to destroy data on virtual
tapes by overwriting it with a random patterns of bits, rendering the data
unreadable.
To shred tapes:
