Example uses of cryptocrypt

You'll find some sample use cases here, derived from real world scenarios. You can use them for inspiration.

You'll notice that the messages never include anything insecure. Even if they fell into the wrong hands, your assets would remain safe.
That's the intended purpose: data stored online should never be enough to derive your key.

Physical backup for an heir who knows about crypto

• You've written your passphrase on a paper, or etched it in metal, or encoded it in some way in the physical world
• The recipient knows about cryptocurrencies, and only needs the location of the recovery passphrase.

Dear redacted,
If you receive this, I've been away for a long time.
We've discussed crypto assets in the past, and you know I own some. Now that I'm gone, you'll need my recovery phrase to access those. In my nightstand, in a black fabric pouch, you'll find an orange paper with 24 words written on it. You can use those with any dedicated hardware wallet to access the funds.
Love you,

• Simple, direct, to the point.
• No unnecessary information that could help an attacker: even if they can read this message in advance, they won't know who you are, or where you live.

Partial physical backup for someone who knows about crypto

• The recipient knows about cryptocurrencies, and only needs the recovery passphrase.
• For safety, four words are not written on the paper, and are instead sent in the message.
  • This is not a perfect failsafe. Someone finding the paper (with 20 words) might still be able to bruteforce the missing four words to access your wallet.
  • However, someone simply finding the four words would be unable to do anything with them.

Dear redacted,
It was good while it lasted... remember when we discussed Bitcoin? I've setup this message to be sent automatically after I pass away.
In our holiday home, behind the washing machine, there's a plastified sheet with 20 seemingly random words.
Here are the four missing ones: umbrella, hamster, you, easily. Add the missing ones in this order after the first 20, and you can use this to restore a wallet. If you're not sure of what you're doing, you can contact Christopher B. for help, I trust him.
Please use the funds as you wish, and don't miss me too much, I'm gone already. Life is short, enjoy it.

Custom wordlist for someone who knows about crypto

• The recipient knows about cryptocurrencies, and only needs the recovery passphrase.
• The user tried to be "smart", and etched the words in metal with a custom algorithm

[initial part redacted]
I've etched my passphrase into metal rings. Each word has its number associated.
For all odd numbered-words (1st, 3rd, etc.), you actually need to use the word that comes right before in the bip-39 wordlist. If you don't do that, you'll get an invalid wallet.

Paper backup for someone who doesn't know much about crypto

• The recipient doesn't know about cryptocurrencies.
  • This is not ideal. You should make sure the recipient at least knows that cryptocurrency exists, and that you have some. You don't want them to think this looks like a scam.
• The user points them towards someone safe who can help

[initial part redacted]
I have a significant amount of money that wasn't stored within a bank, that my executor will not mention.
If you don't do anything with it, it'll be lost forever.
Instead, in the binder where I store my invoices, you'll find an envelope with "TREZOR" written on it. Bring this envelope to Brett, and show him this message. He'll help you.
