BrainWallet Defcon Attack Discussion, Advice, Q&A, Brainflayer Info, etc.

Someone forked Warp Wallet to spit out a 12 word seed (as well as the extended private key), but still haven't found one that directly goes to segwit addresses. You could do a multi-step procedure to use a randomly generated password to spit out yprivs and zprivs if you like to have a segwit brainwallet.

I found these:
https://github.com/Logicwax/PortalWallet <= used older Warp Wallet code, and doesn't have segwit.
https://www.nowallet.org/

The only use-case for a pure brainwallet, as others have mentioned, is when escaping a country or government or warzone with only the clothes on your back. Even in this case, you can probably sew on embroidered password under your clothes or otherwise write it down somewhere on your person.

I plan to release an update adding support for this "passphrase plus xor" brainwallet variant, so don't go using it.

Is this "XOR implementation" really that useless (considering XOR + Warp Wallet variant)?

Thanks @Dabs for mentioning nowallet.org

I just brought back from the ashes my old list of brainwallet projects here: https://bitcointalk.org/index.php?topic=1164163.0

So I'm catching up all those yet operational and working projects...

Yeah, no problem. I have a bunch of older paper wallet generators, some don't exist anymore due to the website disappearing (or removing the files). In the end I'm fairly convinced that using Electrum or one of those Electrum compatible seed generators using your own entropy (if you like to flip coins or roll dice) is more convenient.

I agree 100%!

Generating your own seed/passphrase using diceware (coin flipper, card shuffler, etc) is the safest way to go for sure...

But playing with brainwallets is still enjoyable! (For study purposes of course) 

If you know any other project that I didn't mention on my list, please share!

Cheers!

Where I can find my wallet

[dzxpert]

Please do not take this warning lightly.  Over 800BTC were available for theft (and lucky taken by a whitehat hacker - more information coming soon).  Please ensure that your bitcoins are not part of the ones that are taken in the future.  Save your bitcoins today, and transfer them to a safe storage system such as a Trezor or an Electrum Cold Storage wallet.

I were robbed of 22BTC by most likely a brainwallet cracker is there any chance I could get my BTC back for more info check my thread https://bitcointalk.org/index.php?topic=1146935.0

 well check how much is 22 BTC now
