Step-by-step guide using Vigenère Polyalphabetic Ciphers to encrypt your Mnemonic Seed and prepare it for steganography.

Hi folks,

As of April 2024, the UK police and National Crime Agency were granted new powers to confiscate and destroy cryptocurrency assets, passwords, or hardware wallets without making an arrest:

Police will no longer be required to make an arrest before seizing crypto from a suspect … items that could be used to give information to help an investigation, such as written passwords or memory sticks, can be seized

Whether this will be used to tackle legitimate crime or as an arbitrary blanket procedure to prosecute law-abiding individuals who are concerned about financial privacy is yet to be seen.

What remains is a need for extra precautions to safeguard your Monero.

This is one system that I’ve used and that I want to share with the community.

Thanks

    The first 3 letters are unique for the English seed words, so you just need to encode 25*3 = 75 letters.

    I also think it is worth writing them down in a way that is not obviously a crypto address. You can place 75 letters in a 9x9 square (with maybe some extra dummy letters) that looks like a common word puzzle, eg sudoku or crossword, in a specific order, eg a spiral. You can custom print a template or copy one from eg https://puzzlestream.com/sudoku/blank-grid.php .

      Great idea! yes throwing in random and arbitrary letters can strengthen the encryption. Something I was thinking about was replacing spaces with “-[random text]-”

      Example:

      sdfsdf-iuocbff-oiurwqx-afewef-gupioue

      So the true encrypted text would be sdfsdf oiurwqx gupioue with -iuocbff- -afewef- representing spaces.
