compute checksum word from manually entered incomplete seed #1498

Closed zdeneksvarc closed 3 years ago

zdeneksvarc commented 3 years ago

Is your feature request related to a problem? Please describe. When using diceware I can't compute checksum only with pen and paper. If I don't want to use computer, even offline, I can still use the trezor device. Why don't let the trezor device generate the checksum word from manually entered incomplete seed?

Describe the solution you'd like trezorctl command to turn on Trezor to compute BIP-39/SLIP-39 checksum word from manually entered incomplete seed.

Describe alternatives you've considered Computing checksum word with software utility like bip39check in trusted offline environment like Tails.

Additional context trezorctl get-checksum -w [bip39|slip39] -t [128|192|256]
