This user-friendly website allows you to generate valid cryptocurrency wallets using an image (or any other file) combined with an optional password, rather than the traditional random number generator. Essentially, the wallet seed (24 mnemonic words) is generated from the hash of the file and the password.

There are several advantages in using a file and a password:

• Hidden in Plain Sight: Your file can be any ordinary image or document that can be stored on any device, disguising its critical role in the wallet creation.
• Versatility Against Threats: By changing the password, one file can be the source of multiple wallets. It's virtually impossible to determine how many wallets, if any, originated from a single file. This obscures potential theft attempts, including the so-called "$5 wrench attack".
• Memorability: It's easier to recall an image and a chosen password than to remember a randomized 24-word seed.

1. The chosen file is transformed into a data URL (a string representation).
2. If a password is added, it's attached to the end of this string.
3. The concatenated string is hashed using SHA-256, which then becomes the entropy for the wallet generation. The wallet generation code is sourced from iancoleman's bip39 and bip39-coinomi for Monero.

// All generated addresses are made with BIP44:
// `m/44'/Coin'/0'/0/Index`

Entropy = sha256(FileAsDataURL + Password);
MnemonicSeed = getMnemonicFromEntropy(Entropy);

• File Integrity: Ensure the file hasn't been compressed after you've used it to generate a wallet. It must remain unchanged, byte-for-byte. This is especially crucial for images; popular messaging apps tend to compress them, which would make them completely different to the wallet generator.
• Password Selection: It's crucial to use a password. Phrases, long but memorable, are recommended. For example: "My 3.14 dog thinks about 42 :)." Relating the phrase to the image can aid recall, but adding at least one random number and a special character is a must.
• Device Trustworthiness: Only use this website on devices you trust and preferably offline.
• QR Code Precaution: If you use the QR Code, you need to be careful, some scanner devices may store the scan history.

It couldn't be any simpler. Just go to releases and download the file-wallet.html from the latest release. Now, you only need to open it with any browser you like (double click it).

I recommend storing the exact version you used on your PC for safekeeping.

• Add E2E tests using Cypress.
• Make a standalone .html file.
• Add a loading indicator during wallet generation.
• Find a better way to handle the JS code from iancoleman's bip39. Maybe worth making an npm package.
• Implement a light theme option.
• Add Monero support based on bip39-coinomi.
• Enhance accessibility following WAI-ARIA standards.

Task Under Careful Consideration:

• Use bcrypt instead of SHA-256 for hashing. (breaking change)
• Omit the data:image/png;base64, prefix from FileDataUrl. (breaking change)
