I don't to visit any website. I know how AES works behind the scenes. I don't care what a random website outputs on an arbitrary input.
LOL.
No, it doesn't. Check openssl for example. It comes with literally every linux distro out there.
Yes it does. Windows does not come with it, so you have to download it or similar software. Stop pretending only Linux exists and that everyone uses Linux.
As shown in my previous post, a 12 word mnemonic results in 48 byte which can be easily represented by 48 characters.
openssl enc -k blabla -aes256 -base64 -e -in seedwords.txt -out encrypted_seedwords.txt:
U2FsdGVkX1/boCM0jlccYHbJiy9dEc0fko5UiDWHTIY/au62xL802na5+2osDm7I
3VZ9JuwDob0mK3lT5ygY1ypkm0/Hp+1fsor3kWtzK/E0AE6Bd50n7YFYlvGmnQp4
128 characters.
That is one reason why it is bad.
Another one is that it leaks bits of the plain text.
Any of these 2 reasons is enough to deem that as a bad design.
So BIP-39 is a stupid and bad idea, saving the private key in an easy and human readable format?
It's not.
Simply cryptanalysis and even bruteforcing is enough to break your "scheme".
Yes, after I provided the exact algorithm and hints to make it crackable. Once again:
If I just came here and said "crack this, it's encrypted, good luck lol", absolutely nobody would be able to do it, because the possibilities I could have used to encrypt it are endless. It'd be the same as trying to brute-force Satoshi's private keys.
Just stop pretending your "mechanism" is good. It is not even close to being acceptable.
Still not getting it and missing the point.
