Hello. As you know, there is BrainWallet passphrase, which allows you to store mnemonic recovery phrase in your mind.
Now bitcoin is becoming popular very quickly and there are new users who create wallets and start using bitcoin.
Accordingly, more new users use BrainWallet to create their own PrivateKeys because it is simple to remember.

I did a little work on writing a small application. Which could show users that it's better way to generate a PrivateKey randomly.
With this application, any user can check the pre-created BrainWallet passphrases from the dictionary.

It looks like this.



During the application you can see the addresses of wallets and the balances.
It is simple to use. You create phrases.txt file with mnemonic phrases and the application itself calculates the public addresses and checks it for the current balance.

Dictionary file phrases.txt can looks like this:




Good results (with positive ballance) are stored in the good.txt.
It looks: Private Key (sha256) -  PublicKey - Balance in satoshi.

Having researched the logic of creating BrainWallets, one can come to the conclusion that most users use:

- A string from 12 to 18 characters. For example "mybtcbrainwallet";
- Quotes from films and books. For example, "Your mind makes it real";
- Сombinations of 3,4,5 words. For example, "across foamy when odometer rover".
- А couple of years ago, many used simple words or favorite passwords as BrainWallet mnemonic phrase.

Here is an simple example of phrases.txt based on the aforesaid.



With diligent approach to the generation of phrases for search, you can find several wallets relating to used BrainWallet passphrase.

The result will look like this!:



As you can see, the functionality itself is quite simple, it is only necessary to include your brains in order to find a wallets with a positive balance.

A similar software is used only by individuals. I want it to be accessible for everyone. After all, this will force people to create more complex phrases or use randomly generated keys.
