  if settings.nil? || !settings.get_sp_key
    raise ValidationError.new('An ' + encrypt_node.name + ' found and no SP private key found on the settings to decrypt it')
  end

  elem_plaintext = OneLogin::RubySaml::Utils.decrypt_data(encrypt_node, settings.get_sp_key)
  # If we get some problematic noise in the plaintext after decrypting.
  # This quick regexp parse will grab only the Element and discard the noise.

  # To avoid namespace errors if saml namespace is not defined
  # create a parent node first with the namespace defined
  node_header = '<node xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">'
  elem_plaintext = node_header + elem_plaintext + '</node>'
