Feature Request: Adding BIP-38 passphrase support #180

It would be useful to have support for BIP-38 passphrase. This will help improving security and also enable user to recover existing passphrase-protected seeds

As we've documented in a few other places such as our book on Smart Custody, the fact that there is no checksum on the BIP-38 passphrase makes it risky, and there are many examples of large losses due to it.

The other problem is properly backing up your BIP-38 passphrase.

Our current plan is to add Gordian Envelope support to Seed Tool, which will allow you to do SSKR share backup of more than just your seed, but also other data, such as descriptors, lightning channels, payment comments, etc. that are necessary to fully restore you wallet. Our plan is to first add the ability to backup your BIP-38 passphrase in the envelope, and then add other BIP-38-related features elsewhere in the app.

We are planning a Q2 release for adding Gordian Envelope to Seed Tool.
