An apparatus and a method for validating encrypted archive keys is described. In one embodiment, a passphrase is received. An archive key is recovered with the passphrase. A Message Authentication Code (MAC) value is computed with the recovered archive key. The computed MAC value is compared with a MAC value stored in an archive to determine the validity of the passphrase. The stored MAC value is originally computed with an original passphrase using the archive key as a MAC key. |
