# Introduction

BIP38 is a cryptographic standard that defines a method for encrypting and securing private keys associated with Pay To Public Key Hash (P2PKH) addresses. It provides a way to create encrypted versions of private keys, which can then be decrypted using a passphrase, adding an additional layer of security for storing and transmitting private keys. By encrypting a private key with BIP38, users can protect their funds even if the encrypted private key is exposed, as an attacker would still need the passphrase to decrypt the private key and gain access to the associated funds. BIP38 encryption is commonly used for creating "paper wallets" or physical copies of private keys that can be stored offline for enhanced security.

Building on this, our project delivers a robust BIP38 toolkit supporting both EC and non-EC-multiply encryption modes, designed for secure encryption and decryption of private keys across over 150 cryptocurrencies. This library and desktop app simplify private key management by enabling encrypted passphrase-protected storage in Wallet Import Format (WIF) format, with guidance for setup and secure offline storage.
