@fintoda/react-native-crypto-lib v0.5.1

Overview

This module is a native wrapper for cryptographic functions, leveraging Trezor Crypto and secp256k1 libraries written in C. It is designed for use with React Native, providing highly efficient and secure cryptographic operations directly on mobile devices. This module is especially useful for blockchain-based applications and cryptocurrency wallets.

Features

  • SHA3-256, SHA3-512
  • KECCAK-256, KECCAK-512
  • RIPEMD160
  • HASH256 (double SHA-256)
  • HASH160 (SHA-256 followed by RIPEMD-160)

• HMAC:

  • HMAC SHA256
  • HMAC SHA512

• PBKDF2:

  • PBKDF2 with SHA256
  • PBKDF2 with SHA512

• AES Encryption:

  • AES-256-CBC: Encrypt and decrypt data using AES with 256-bit keys in CBC mode.

• BIP Standards:

  • BIP32: Hierarchical Deterministic (HD) wallets.
  • BIP39: Mnemonic phrases for deterministic key generation.

• Digital Signatures:

  • ECDSA: Sign and verify messages using the secp256k1 curve.
  • Schnorr Signatures: More compact and efficient signatures with support for signature aggregation.

• ECC Interface for bitcoinlib-js:

  • Provides an interface for using native ECC operations with the bitcoinlib-js library.

Why Use This Module?

• Performance: High performance through native C implementations of cryptographic algorithms.
• Security: Based on reliable and secure industry-standard libraries.
• Compatibility: Works seamlessly with various Bitcoin standards and integrates with bitcoinlib-js.
• Cross-Platform: Supports both iOS and Android with a unified JavaScript interface.

Installation

npm install @fintoda/react-native-crypto-lib
# or
yarn add @fintoda/react-native-crypto-lib

Usage

import { Buffer } from 'buffer';
import { digest } from '@fintoda/react-native-crypto-lib';

// ...

const data = new Uint8Array(
  Buffer.from(
    'ab7615a6cb35f59c2c0a2e9d51d2bf2f20366b0fc1e27a30e3e25cfd65b5f5c3',
    'hex'
  )
);

const result = digest.createHash(digest.HASH.SHA256, data);
