| 2 | """Create a Steel wallet in the rig. |
| 3 | |
| 4 | Wallet creation reads a choice and an admin name from stdin, then prompts twice |
| 5 | for a passphrase through crossterm's raw mode -- which needs a real terminal, so |
| 6 | a pipe will not do. This gives it a pty. In raw mode Enter arrives as a carriage |
| 7 | return, not a newline; a newline is not a submit and the prompt simply waits. |
| 8 | |
| 9 | The passphrase is a throwaway for a wallet that lives for thirty seconds and |
| 10 | holds nothing. |
