Frequently asked questions

      

        
Are these keys safe for production?

        
The randomness is strong, but real keys must be issued and stored server-side. Use this for prototyping.

        
What format is the key?

        
A base64url string (URL-safe, no padding), prefixed with bk_ for readability.

        
How long should an API key be?

        
At least 32 random bytes; longer is better. This tool defaults to 32.
