I sent a btc to my offline armory. Unfortunately I haven't enough date to download 150gb date. I read I need to transfer the keys. If somebody can tell me how to do it. I can't find some phrases.

Greetings

When I try to export the keys armory ask me about passphrase. What does it mean.

And Exodus speakabout error by Non-base 58 character?

Greetings

So if I understand well I have two ways to get back my btc:
- download 150 gigabyte date
- export the keys from Armory and receive btc on another client like etherum
