blocksmith's Issues

No module named secrets

Hello, this code looks interesting and potentially useful, however upon installing in python 2.7 on linux -- Ubuntu 18.1 there's the error No module names secrets. There an issue in line 1 of init.py - from.generator import KeyGenerator and line 3 of generator.py for import secrets.

Note that there were no errors during installation. It's just the above issues after trying to 'import blocksmith'.

How to generate the private keys that begin with "L" or "K"

https://bitkeys.work/?page=0
I wanted to generate the private keys like above which begin with "L" or "K"
Then my code is like this:

`kg = blocksmith.KeyGenerator()

kg.seed_input('35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP') // the parameter is a bitcoin address

key = kg.generate_key()

print("key is: ", key)`

The output is:
key is: 0787aa5c4ab37dea0e87073cbc901d8b27d2e861f833673157878c019484e3bd
It doesn't begin with "L" or "K", can you help please? thanks a lot
