Security-sensitive tools need to express themselves as such
Since this repo is specifically for learning purposes only...
Must assume that users might be clueless regarding how sensitive some tools may be to their own security.
At the least they need to be EXTRA-LOUD before asking for private-key material.
- generate_keys should by default only leave an ewif on disk... prompt EXTRA-LOUD for less-safe keychain files.
- anytime that a private-key or seed is requested (or loaded into memory)... loud security warnings.
After all... this is about learning... therefore INSTILL BEST PRACTICES!!!
