DS Header Question

[akrsoTale]

Hello developers, I had noob question..

I am Asia server user(OS), and I confused DS header signing code
It is scenario :

[GET] : https://sg-public-api.hoyolab.com/event/game_record/hkrpg/api/rogue_nous?server=prod_official_asia&role_id=833539344&need_detail=true

DS - 1736438544,n5NZkp,7d61ae0898dcd7369b61858048a7036b

I was capturing in my browser network log,

But, I could not hashing that sceniarios.
I expect the salt value to be problematic.
I was trying these strings:

• salt={salt}&t=1736438544&r=n5NZkp
• salt={salt}&t=1736438544&r=n5NZkp&b=&q=need_detail=true&role_id=833539344&server=prod_official_asia
• salt={salt}&t=1736438544&r=n5NZkp&b={}&q=need_detail=true&role_id=833539344&server=prod_official_asia

And I replace {salt} on these strings:

Question 1.

• What is SaltConstants.ENUMS? just enum string? Just I change string like salt=OSLK2&t=1736438544&r=n5NZkp?

Question 2.

• Or I mistake string manipulation? or else?

Thanks for your service and Please answer my dumbs question OTL...

hoyolab api need to use OS salts, and different hoyolab version use different salt, hoyolab web uses web salts rather than app salts.
And we uses app salts internally

If you try to reverse the salt the request uses, you need first check x-rpc-app_version header, and narrow down the salts might be used.

If your request is captured in browser, it mostly uses web salts, and we currently don't know much about.
