 * Returns a {@link Hash Hash} instance representing the already-hashed AuthenticationInfo credentials stored in the system.
 * <p/>
 * This method reconstructs a {@link Hash Hash} instance based on a {@code info.getCredentials} call,
 * but it does <em>not</em> hash that value - it is expected that method call will return an already-hashed value.
 * <p/>
 * This implementation's reconstruction effort functions as follows:
 * <ol>
 * <li>Convert {@code account.getCredentials()} to a byte array via the {@link #toBytes toBytes} method.
 * <li>If {@code account.getCredentials()} was originally a String or char[] before {@code toBytes} was
 * called, check for encoding:
 * <li>If {@link #storedCredentialsHexEncoded storedCredentialsHexEncoded}, Hex decode that byte array, otherwise
 * Base64 decode the byte array</li>
 * <li>Set the byte[] array directly on the {@code Hash} implementation and return it.</li>
 * </ol>
 *
 * @param info the AuthenticationInfo from which to retrieve the credentials which assumed to be in already-hashed form.
 * @return a {@link Hash Hash} instance representing the given AuthenticationInfo's stored credentials.
