Like this product, there are many other products that focus on allowing one to back-up crypto-currency wallet seed phrases. However, they all have in common the following major disadvantages: * cost -- I can't see myself paying 50+&#x2

Please see my reply to this other similar question: > Looks like a new 2d barcode format to me. Why I would want this rather QR or any other that have redundancy built in? https://news.ycombinator.com/item?id=44145202#441

Initially the bits were counted from 0, however this had two issues: * using 0 as starting point would immediately trigger one's "computer science" instinct, and then it's uncertain which bit is actually bit `0`? the le

With regard to the puzzle idea: if the secret is quite sensitive, and assuming you split the card in say 4 parts, then coercing 2 of them to reveal their puzzle pieces, would reduce the brute force security of the secret from 128 bits to j

The only one minor issue with this snippet (which I now just realized), is that if the secret has the first few bits on zero (i.e. anything that starts with something under `7`) then the resulting bits would be less than 128, and thus the u

> Cool but wouldn’t you forget how to decode it after some time? Not necessarily. First of all there isn't much decoding to be done: if one follows the recommendation, and one uses the hex input variant as the password (or secret),

If the CNC machine is not connected to a network, and (I don't know much about CNC, but I do wonder) if one can provide a generic program, then just fill in the parameters before execution, right at the machine, the secret would be con

This is how much I could pack on a standard (CR80 ID) card sized plate, while still being able to punch the holes without power (or precision) tools. (The aspect of ease of creation with household items was paramount for my design.) There

There is: * press `reset` (to clear the checkboxes); * press `tab` (to select the first checkbox); * if the current bit is `1` (i.e. there is a hole in the pattern), press `space`; * move to step 2 (i.e. press `tab`);

Indeed, this is another use case I've had in mind. (Protect a X25519 private key, and use the public key to encrypt against, without the need to have the private one online.) However, the current scheme supports only 128 bits, thus re

Besides the issue with printing and paper longevity, another issue with QRCodes is that you can't easily convert them back to data without a proper application that implements the decoding algorithm, and thus you need to extend your tr

Provided that the information one wants to keep safe is sensitive and important long term, there are two main issues with printing (either text, QRCode, or anything): * (paranoia) can you trust your printer not to leak the secret? (either

I don't see how respecting one's rights (in this case one's copyright over his own works) leads to having revoked the right to buy books. I agree that it is sad to see many online book stores moving from "selling" t
