The code can potentially find an address after replacing hexadecimal characters in the string generated from the secrets module. It may find the address or key in the 7th or 8th while loop, for example.
Running the code with "1" as to generate output I got 0.065 execution time.
Calculating the additional range that it searches is very small compared to the overall bits.

I have no good reply to "why should we use it?" I had mentioned the idea and felt I should share the code for example.
