What is this, lol, a site called "cryptosec" advises people to use this crappy cipher to protect their seed - what a joke! Even Caesar cipher would be better in this case, because an attacker would have to spend a few miliseconds to bruteforce it.
If some newbie is reading it and thinks it's a good idea, this can easily lead to lose of money in the future, because the method proposed is not encryption, it's just a very weak attempt to hide the seed. Do not use any methods you read from random sites on the Internet and do not invent your own schemes, instead research strong cryptography if you want to truly protect your secrets.
Hey hatshepsut93!
Not sure if you've misunderstood the article, but with all due respect, it was emphasized very clearly on the article AND this topic title that this method is just to make it a bit more difficult for a person to gain access to your funds if they somehow got access to your
written word backup paper; and it was also mentioned that applying such method doesn't make storing your word seed online a good idea(because it never is).
In our opinion, using this very simple method is still better than simply nakedly writing your 12-24 word seed on a piece of paper.
Have a great day!
