<a class="mention" href="/@monbon">@monbon</a><a class="mention" href="/@glauce">@glauce</a> and everyone I can help you: Be careful with your data, and especially with your used device. Turn on your computer, change the time in the BIOS, then create your seeds with it on this same computer while being offline (disconnecting the wifi physically is a plus), export the key in aka cold storage device or list in wallet paper or encode in zip, rar* then launch a system restore on this same your computer to go back to a previous day or week, then restart and access the BIOS and reset the correct time. (*changing the time of the bios can be very useful if you use 7zip to encode your seed file in a folder encrypted with a password e.g. *#911#Hello-Poto* (mnemonic) can be a good password. Be aware that "zip, rar...." files with high encoding are crackable depending on the time when the file was created, with my method you will voluntarily truncate the metadata with the clock without it being visible it&#39;s a true/false/positive). Another very powerful (home-made) variant of the wallet paper: you can encode your word list directly dispatched to specific places in the metadata and increment it into an image file or a photo on your digital photo card at home or even your public profile photo (less secure but accessible everywhere), (EXIF is an option) so your treasure remains accessible there before your eyes. If you want to add an extra level then nothing prevents you from using variants for example: the reverse of a text like this: Hello World &gt; blɿoW ollǝH if you want to add more + I suggest the foreign language of your choice + reverse, here the example is translated in Samoan language + reverse &gt; iϱɒlolɒl ɒʇolɒT or in Moari &gt; oA ɒɿO ɒiꓘ = Hello World or even in Malayalam reversed &gt; ്ഡൾേവ ാേലഹ = Hello World. Even a software decrypt next genN.SA fueling the AI worth billions of dollars still scratches its head, and yet. It&#39;s my personal method for home-made encryption/encoding if you want to add one more level nothing prevents you from encoding the result language + reverse in binary then in SHA256, 512.... these my unconventional methods (which I invented in 2008 like other things), I pass it on to you, as long as it&#39;s useful to you, to all of you, made in good use, it&#39;s patentable (I have no budget, for nothing by the way, lol). Made in good use!
