Is it possible to generate 256 character Splunk authorization token

[krishnabv]

Hi Team,

I am creating authorization token from Splunk web and I received the token which consist of more than 256 characters. 

Is it possible to reduce its length or any alternative approach by which we can generate the token up to 256 characters! because my tool have limitation that it cannot accept more than 256 characters as token

Thanks,
Venkata
