support direct conversion from sskr to bip39 #61

Closed masha256 closed 3 years ago

masha256 commented 3 years ago

I confirmed this can convert a file of sskr shares back to bip39 correctly:

cat shares | seedtool --in sskr --out hex | seedtool --in hex --out bip39

but when trying to convert the same sskr shares file directly to bip39, I get:

cat shares | seedtool --in sskr --out bip39
seedtool: Input format sskr cannot be used with output format bip39

Is there a reason for this?

Being able to convert directly from sskr to bip39 seems like one of the most common use cases. I want to provide sskr shares to my family members in case of an emergency and have a single command they can come together and run to convert this to a bip39 seed phrase that can be used by many wallets.

It would seriously complicate the design, coding, and testing of seedtool to be able to convert anything to anything. And since it is a command line tool that supports stdin and stdout and thus unix piping, I made the choice to keep its design simple and limit the conversions available to and from the most basic. If you have a particular common use case for you, just code up a single-line shell script.
