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

Thanks, glad you found something useful in it.

I'm not sure, I'll have to look into polyseed. I guess the over all point is to take elements of this and make it your own :)

My key focus, as you pointed out, was not to use any third-party software or technology. Trying to think of a "worst case scenario" that provides decent encryption while also only needing a memorisation of a short password and a pen/paper. You could write out the Vigenère Table by hand if you really wanted to.

Next, in this line of thinking, I'll do something on the Playfair Code which was used by the British during the Boer War and by German spies during WWII
