/**
 * <p>
 * Represents a collection of Secure Keys and typically stores them in some
 * persistent storage. SecureKeyStore isolates from particular DB implementations.
 * A Secure Key Store need not implement any security itself, it just holds keys
 * that are inherently secure (like SecureDESKey).
 * </p>
 * <p>
 * Note: SecureKeyStore doesn't have any relation with java.security.KeyStore
 * SecureKeyStore works on objects of type org.jpos.security.SecureKey
