How to create Ethereum brain address? I have used bitaddress.org to create a brain wallet for my Bitcoin.
Now I would like to create a brain wallet for my Ethereum using Bitcoin Improvement Proposals (BIP) 32/39/44/49 technologies. Is there any reputable tool (preferably similar to bitaddress.org) or open source command line tools I can use to generate a brain address for Ethereum?

Thank you all
Don't use a sha512 brainwallet generator like bitaddress.org to generate your brainwallet. Many people have lost their money by doing so.

Instead use a more secure salted scrypt like warpwallet.

For Ethereum, I made a warpwallet implementation here, that is available as a web version and as a go executable. For extra security you should generate the addresses offline.
