negative.code: %% Function: make_base64_md5_token(In)
  %%           In = term(), indata - anything accepted by erlang:md5()
  %% Descrip.: Make md5 of input, base64 of that and RFC3261 token of
  %%           the result. Tokens are case-insensitive, so we lowercase
  %%           the ones we generate here to make them easier to read.
  %% Returns : Result of make_3261_token()
