Storing and Managing Your Password with keepmesafe

How to Store the Password

Upon setup, you'll be prompted to insert an encryption password. A 32-character hexadecimal password is generated if you don't provide one.

Where to Store the Password

The encryption password will be stored in a .password file in the root directory where you run the tool.

Extra Security Tips

Backup your .password file. Maintain strict Access Control. Consider External Storage for the .password file. Note: The .password file is automatically added to .gitignore.

Using Functions in Your Code

Retrieving Encrypted Private Key

Use betterKey or betterKeyAsync to decrypt and retrieve your private key.

import { betterKey } from "keepmesafe";

const fetchKey = async () => {
  const key = await betterKey("accountName");
  // Output: decrypted key
};

fetchKey();

Convert your private key back to hexadecimal

const fetchKey = async () => {
  const key = await betterKey("accountName").toHex();
  // Output: hexadecimal key
};
fetchKey();
