This Python script generates BIP39 output indexes from a given seed phrase. These index numbers can then be stamped into stainless steel washers as a way to store your seed phrase that is safe from fire corrosion and floods. Step-by-step instructions can be found here https://blockmit.com/english/guides/diy/make-cold-wallet-washers/ . The following two YouTube videos give you examples on how to create your own. These examples stamp the Seed phrase Word into the washer. This can be very time-consuming for long words. This script converts your words into the bip39 index number so you can just stamp the number instead of your seeded word. This adds an extra layer of security as many people wouldn't know What a bunch of washers and numbers are https://youtu.be/EEyz7p9Aci8?si=DTWno46ocGE5nzQa https://youtu.be/3Aj_EHOu9WE?si=VRtZhSvuVW5_wwhU It runs 100% locally and does not access the Internet. CAUTION! Never enter your seed phrase into a webpage online. You can never trust where the information is going.

To install BIP39 Output Generator, follow these steps:
- Clone the repository:
git clone https://github.com/yourusername/bip39output.git
- Navigate to the project directory:
cd bip39output
The script defaults to 24 words seed phrases. If you have 12 words then Change the variable in the script from 24 to 12.
NUM_WORDS = 24 # Number of words in your seed phraseChange it to
NUM_WORDS = 12 # Number of words in your seed phraseTo use BIP39 Output Generator, follow these steps:
python getNumbersfromSeed.py2. If you have not hardcoded your seed phrase in the script, you will be prompted to enter it as follows:

python getSeedfromNumbers.py
input 12 numbers from your stainless steel washers that correspond to words in the bip39 word#list
The App Will look them up in A local copy of the bip39 wordlist to find the corresponding words. It will then Print the words and their index numbers.
It does this all locally , not on the web. **CAUTION!** Never enter your seed phrase into any website or app that is connected to the Internet
The example below is what you get if you use the test seed phrase. Comment the line in the script to enter your own Numbers.
