 * Entity Bean representing a table protection entry in the log database.
 * Information stored:
 * <pre>
 *  id (Primary Key)
 *  version versioning of the protection rows (this row), so that the underlying database table can be upgraded and still verified.
 *  protectAlg hmac, rsaWithSHA1 etc. Also used to implicitly define the key type of the protection key.
 *  hashVersion versioning of the protected row, so the underlying database table can be extended and still verified
 *  hash hash of the row data from the underlying table to be protected.
 *  signature actual signature.
 *  dbKey database key of the underlying row that is protected, used to find the row for verification.
 *  dbType type of object protected, determined by the OBJECT, for example LOGENTRY
 *  keyRef reference to key used for protection.
 *  keyType type of key which the reference refers to
