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.
