How do I identify the valid checksums for bip39 if I generate 11/12 of the word?

Hi again everyone,

I was hoping to get someone to double check the hash done on entropy in hex that I generated that is converted to F2B173C5D5AAFFEBB80425FF5FE2057C.

As per hosseinimr93's post, this translates to a SHA256 digest of 931258d717865a310cfc24a9161b21f4c0d02e0bb4cf12894516170a10e72339

Also, with the help of o_e_l_e_o , I was able to perform the following commands and was able to successfully load the Linux files into my Windows copy after logging into su:

apt-get install libdigest-sha-perl

I next performed the following commands but see a different SHA256 digest as noted below:

└─# echo -n F2B173C5D5AAFFEBB80425FF5FE2057C | shasum -a 256 -0
362695f3d7e699ecdae3536168fdc0f4e5696a1ee278c4800a626c0bac70746c ^-

I'm wondering why the discrepancy is occurring with hosseinimr93's SHA256 digest as from what I understood from
o_e_l_e_o :

"-a selects an algorithm, in this case 256. -0 tells it to read the input as bits, which is necessary when computing a checksum as above."

TIA

Because the -0 argument tells it to run in bits mode, but in your command you are not feeding it a string of bits, but a string of bytes. You need to feed it the entropy in 0s and 1s as I said before:

Code:

echo -n "11110010101100010111001111000101110101011010101011111111111010111011100000000100001001011111111101011111111000100000010101111100" | shasum -a 256 -0

Try this command and see if you get the correct checksum.

That did it!  Thank you very much!  So in summary (for the future folks here) on a Windows terminal I had to run through a few hoops here to get things setup.

- I first had to enable Windows Subsystem for Linux

- I then downloaded Kali from the Microsoft store.

- Next I had to setup Kali and create a username and password.

- I next had to log into su via the sudo su command

- Finally I performed the apt-get install libdigest-sha-perl command on the WSL window in sudo su mode and it installed all the necessary commands needed to perform the following line that resulted in the correct SHA256 has of my binary input:

└─# echo -n "1111001010110001011100111100010111010101101010101111111111101011101110000000010 0001001011111111101011111111000100000010101111100" | shasum -a 256
 -0

Thanks again to everyone who helped me along here.  It was very educational!

Glad you got it all figured out.

For future, if you are planning on using this method (coin flips, calculate checksum, convert to seed phrase manually) to generate a seed phrase, then you should do it on a device which is permanently airgapped. That means it does not have an internet connection and it will never have an internet connection again. Even better if you physically remove things like the WiFi card and Bluetooth chip to ensure it has no wireless connectivity whatsoever. You should also make sure the device is completely clean, which means formatting it and installing a clean OS on it. If you are going through all this trouble anyway, then you would probably be better served simply installing a reputable open source Linux distro rather than Windows and Linux on top. There are a number of very easy to use Linux distros. Mint is probably the closest to Windows in terms of look and feel.

Thank you for the suggestion. Question, what are your thoughts about putting into a Linux Tails Distribution on a Windows machine via a USB drive? I'm considering trying to use a persistent drive on a Tails distribution and not connect the Tails OS to any internet connection and then run it through this os. Are you aware of any possible security issues with this configuration? Thanks

Question, what are your thoughts about putting into a Linux Tails Distribution on a Windows machine via a USB drive?

Do you mean running Tails as a virtual machine within Windows? Or do you mean bypassing Windows altogether and simply booting the computer from the Tails USB? I wouldn't recommend the former, but I suspect you are talking about the latter.

If you boot to Tails, therefore completely ignoring Windows, and never connect to the internet or any other methods of communication while within Tails, then this is certainly a safer option than simply using Windows, and a good option if you cannot dedicate a device to be permanently airgapped. It would be even better if you can physically disconnect any connectivity hardware (unplug Ethernet cables, disconnect WiFi modules, etc.) and better still if you can physically disconnect any persistent storage (such as your hard drive(s)) while you are using Tails. But obviously the best option would be if you can dedicate an old machine to do this on which will never boot Windows or go online ever again.

Hello, yes I was talking about botting into a USB drive tails OS on pc or laptop that already had an OS installed on it.  But thank you for the clarification and additional pointers.
