node-cardcrypto

node-cardcrypto is a comprehensive Node.js wrapper for cryptographic operations, specifically tailored for smart card, EMV, and payment terminal domains. It provides an intuitive API that seamlessly handles both Hexadecimal Strings and Buffers, making it easy to perform various encryption, hashing, padding, and MAC operations.

Overview

This library wraps essential cryptographic functions into a single, easy-to-use package. It is designed to simplify cryptography tasks commonly found in financial applications and APDU communications.

Key Features

  • Symmetric Encryption: Supports DES, Triple DES (3DES), AES, and SEED (South Korean block cipher algorithm).
  • Asymmetric Encryption: RSA encryption support (Public/Private Key, CRT) via the node-jsbnrsa module.
  • Message Authentication Code (MAC): Implementations for DES MAC and various HMACs (HMAC-SHA1, HMAC-SHA256, HMAC-MD5) to ensure data integrity.
  • Hashing: Common hashing algorithms including MD5, SHA1, and SHA256.
  • Padding Schemes: Extensive support for padding data blocks, including ISO9797, 80 Padding, PKCS#5, and PKCS#7 padding.
  • Utilities: Random byte generation and bitwise operations (e.g., XOR).

API Reference

DES (node-cardcrypto.des)

  • ecb_encrypt(key, msg) / ecb_decrypt(key, msg)
    • key(String | Buffer): 8 bytes (DES), 16 bytes (2-key 3DES), or 24 bytes (3-key 3DES).
    • msg(String | Buffer): Data to process. Length must be a multiple of 8 bytes.
    • Returns: Hexadecimal string of the resulting data.
  • cbc_encrypt(key, msg, iv) / cbc_decrypt(key, msg, iv)
    • iv(String | Buffer): Optional. Initialization Vector (8 bytes). Defaults to 0x00....

AES (node-cardcrypto.aes)

  • ecb_encrypt(key, msg) / ecb_decrypt(key, msg)
    • key(String | Buffer): 16 bytes (AES-128), 24 bytes (AES-192), or 32 bytes (AES-256).
    • msg(String | Buffer): Data to process. Length must be a multiple of 16 bytes.
  • cbc_encrypt(key, msg, iv) / cbc_decrypt(key, msg, iv)
    • iv(String | Buffer): Optional. Initialization Vector (16 bytes). Defaults to 0x00....
  • ctr_encrypt(key, msg, iv) / ctr_decrypt(key, msg, iv)
    • iv(String | Buffer): Optional. Initialization Vector (16 bytes).

MAC (node-cardcrypto.mac)

  • hmac(type, key, msg)
    • type(String): Hashing algorithm (e.g., 'sha1', 'sha256', 'md5').
    • key(String | Buffer): HMAC secret key.
    • msg(String | Buffer): Message to authenticate.
  • des_mac(key, msg, iv, len) (FIPS PUB 113 / CBC-MAC)
    • key(String | Buffer): 16 bytes (2-key) or 24 bytes (3-key).
    • len(Number): Optional. Output MAC length. Default is 4 bytes.
  • des_mac_emv(key, data) (ISO/IEC 9797-1 MAC Algorithm 3 / Retail MAC)
    • key(String | Buffer): 16 bytes (2-key).
    • data(String | Buffer): Message to authenticate.

Seed, Hash, and RSA

The library also exposes seed, hash, and rsa modules with comparable straightforward parameter structures (e.g., seed.ecb_encrypt(key, msg), hash.sha256(msg)).

Installation

You can install the package via npm:

npm install node-cardcrypto
