Things to consider
Legacy does NOT store any data.
You need BOTH keys and the encrypted seed phrase to decrypt.
If any one of these pieces of information are lost, the Bitcoin is irretrievable.
You have sole responsibility for maintaining your keys and encrypted seed phrase.
Keeping a working copy of "Legacy-offline" is also recommended to decrypt the seed phrase.
This tool is intended to be used in conjunction with a Deadman Switch to deliver the Benefactor Key and Encrypted Seed Phrase.
The security of this protocol depends entirely on the strength of your keys — and that's yours to define. There's a tradeoff between brute-force resistance and memorability, and Legacy lets you choose where on that scale you sit. See Choosing Your Keys to find your spot.
