Abstract

Systems and methods are provided for encrypting data, generating encryption keys, and generating encryption indicators. The encryption indicators may be stored on a storage medium in a location separate from the location of stored encrypted data. The encryption indicator includes information indicative of the encryption key used for encrypting and decrypting the data. In one example, the storage medium is a tape, and the encryption indicator is stored in the user header label of the tape.
