iOS Question B4i have hash key in signkey?

[webhost.company]

In Android, We can extract hash or md5 key from signkey and signkey is secure and I use it to encrypt data and send it to the server for validation
You know nobody can see sign key hash and cannot hack
Is there a hash key for B4i?
How do I can get the special key (md5 or hash) from the signkey and encrypt my data and send it to the server?
Or Is there a unique value for each iPhone for use in-app? example Mac Address or other
I cannot use fake id example UUID
That be real and don't changes
Thanks

This solution isn't too secure. Anyone with access to the APK can find the signature hash very easily. It is not a secret value.

I don't use directly hash in my code
I extract hash key from file with CheckSignutre library
Does hacker can access to it?
I thought nobody cannot access to it

Typically are used generated by server access and refresh tokens without encoding data. First time user types a phone and receives a password by SMS. When user enters this password, a server returns initial access and refresh tokens.
