hello,I'm Joe.I have a simple and easy-to-remember personalized mnemonic generation scheme. Users can customize any sentence, support multiple languages without language restrictions, map out the corresponding mnemonic, and thus replace the mnemonic's memory.

This is an upgraded version based on the BIP-39 proposals, making it easier and more effective for users to obtain their mnemonics, without worrying about forgetting the mnemonic, or even without having to write down the mnemonic. It only requires the user to remember the customized sentence.

The principle of the code mainly involves processing the user-defined sentence with the sha256 algorithm to generate corresponding entropy, and then obtaining the corresponding mnemonic through entropy. This method is fully compatible with the bip39 proposals.
