Makes you wonder how difficult it would be to make a QR and software that gave 3 different seeds.

1) Fully unencrypted, but valid, this way if someone finds it they get whatever little amounts of crypto you had on it. (Hot wallet)

2) Encrypted and you have to enter a password to get that seed. (Warm wallet)

3) Encrypted, but you have to scan with a different piece of software and enter a password that then generates another QR code that you then scan with something like Krux (cold storage)

Might be more Rube Goldberg then really needed but seems like an interesting concept.

You're on the right track - but don't think of it as a QR code. Think of it as data. A QR code is just a visual representation of data. Scan the code to transcribe the data.

I would think of it like this:

How difficult it would be to make a string of data that can be recovered two different ways:

1) Unencrypted, but valid. For example, as a decoy seed.

2) Encrypted and you have to enter a decryption key to get the real seed. A decryption key is just a password or passphrase. It's whatever you set up as the decryption key.

As for your original #3:

You can do that now, with Krux. Here's how.

Create an encrypted QR code.

Let's say this is your seed phrase:

"maid water stomach exhibit much wood useless blood debris reject either green"

To make this easier to talk about, let's call that seed phrase "Green."

And let's say you want to protect it with a crazy strong passphrase. Use Krux to make an encrypted QR code for this long passphrase (which is actually a seed phrase):

"claim pigeon depth cook clerk paper merge bachelor winner patrol surprise muffin"

To make this easier to talk about, let's call that passphrase "Muffin."

And let's say this is the decryption key for Muffin:

"nine sky red truck"

Here's the magic: Use Krux to create an encrypted QR for your Green seed phrase, using Muffin as the decryption key (the passphrase).

So... to decrypt your seed phrase, you'd use 2 Krux devices.

Krux A: Scan Muffin and enter the passphrase to decrypt it: "nine sky red truck" Then have Krux show you a plaintext QR code for Muffin.

Krux B: Scan your Green seed, then scan Muffin on your other Krux to decrypt it.

EDIT: This is a conversation for a different thread. Check out Krux. There are a few Krux threads here. And like I said, there's a SeedSigner fork to add this functionality as well. Highly recommended.
