Anyone can fork it, turn it malicious and trick you into using it if you don't understand the underlying code. This script does not require any networking modules to function (except 'socket' to check for and warn you if you are connected to the internet, see line 54 in seedshift.py). For safety reasons you should only run this script on an air-gapped computer that is not connected to the internet (do NOT reconnect this computer to the internet without wiping/reformatting it first). A better option would be to just do it manually with the \"mapping table.txt\" file, but do not use Ctrl-F to find your words, as even that can be a security risk. Make sure to write down the encrypted seed words, numbers or codepoints by hand, do not print them. Even better, stamp or engrave them on titanium plates to protect from fire or water damage. Note that the encrypted words/numbers are not cryptographically secure, as they can be bruteforced to get the original words, but they do give you some protection from the common thief and some extra time to react in case of theft, etc. For reference, with 2 dates in 1900-2021 range there are about 1 billion possibilities (crackable in days), with 3 dates it's 14 trillion (crackable in years), and with 4 dates it's 158 quadrillion (crackable in the distant future with a supercomputer...), assuming the thief knows the seed words are encrypted and by what method in the first p","default_branch":null,"files":null,"tree":[],"storefront":"/r/mifunetoshiro","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/mifunetoshiro/Seedshift/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
