One feature that would be neat in this toolkit: taking a WIF, extracting the private key, then being able to use that to generate a new WIF of a different coin.
As much as I’ve walked thru the WIF format (and the cointoolkit code), I don’t quite understand why WIFs aren’t directly usable between coins – where exactly the coin ID is incorporated into the WIF in some way.
The use case would be: for anyone who already has a private key, to generate the “like” private key in another coin. Similar to the custom seed / brainwallet idea, it makes for less secrets to remember / record.
Edit: I wrote too soon. I see the current version has “This is a 64 char hex private key” which can serve this function
