I don’t like the idea to store on paper the seed words as I may loose that paper.
I would make lots of copies but then the fear that someone may find one of the many copies is even worse.
I would like to encrypt those seed words so that I can store them even on-line in emails and in many other places so that it is unlikely I will loose it and if someone finds them, they won’t be able to do anything with it.
with the words I would store a few questions that I only know the asnwer of as:
1.The name of your first crush?
2.The nickname they gave you in 3rd grade?
3.The motorbike you always wanted to buy?
4.The year you shaved for the first time?
and much more if possible.
then I will concatenate the question words down on a piece of paper:
and make them in butch of 8 characthers:
…and repeat if necessary
Then I will use the spreadsheet in attachment to encrypt the seed words one by one, inserting 8 characters from the question words per time (so not to insert them all at once) as encrypting keyword for each seed word.
Of course if the question words are not enough or not matching, I will just repeat the letters until it does match as in the example above.
The question is:
is it safe as a process? can I be confident that having the encrypted seed words public or almost public is going to be safe?
Feel free to use and share my spreadsheet and method.
Also what is the difference between doing the above for the 12 words of a normal wallet and the 27 words of the paper wallet? is a paper wallet more secure just because it does never store the keys on computer?
