brainflayer VS py

For pre-HD wallets, see brainflayer https://github.com/ryancdotorg/brainflayer

If you want to use a password like this consider a key derivation function like pbkdf2. (This does not make it safe but you begin to stray away from old brain wallets that are all compromised already see https://github.com/ryancdotorg/brainflayer )

Your wording attempts to fool people into using brainwallets by appealing to ego. Nobody has the ability to make a passphrase from their brain with sufficient entropy to be secure. Stop promoting insecure methods https://github.com/ryancdotorg/brainflayer

Brainflayer is a Proof-of-Concept brainwallet cracking tool

Brainflayer is still running, but does not find new keys because the whole world switched to deterministic wallets https://github.com/ryancdotorg/brainflayer

Brainflayer discovers single keys created by hashing low-entropy "brain passwords". It pre-dates HD wallets, pre-dates SegWit https://github.com/ryancdotorg/brainflayer

Brainwallet normally means something easy to remember, and therefore easy to brute force. See brainflayer, a tool for stealing coins from brainwallets https://github.com/ryancdotorg/brainflayer

People don't talk about brain wallets because nobody uses the same definition. The commonly accepted definition, from when they were popular, is "easy to remember, easy to steal". See brainflayer https://github.com/ryancdotorg/brainflayer

Elliptic Curve Integrated Encryption Scheme for secp256k1 might work for you. It is based on a key exchange you need the private key of one and the public key of another. This would work with Ethereum address keys (and Bitcoin). This makes a 256bit key which can be used for AES encryption for example. Checkout this implementation + the readme is a good explainer: https://github.com/ecies/py
