A JavaScript library providing an easy interface for working with subtle crypto.

Description

EZ_WEB_CRYPTO is a class designed to simplify interactions with the Web Crypto API. It offers a straightforward approach to performing common cryptographic operations such as encoding, decoding, encryption, and decryption in both browser and Node.js environments.

Features

• Automatic environment detection (Browser/Node.js)
• Base64 and Uint8Array conversions
• HMAC generation
• Data hashing with SHA algorithms
• Password-based encryption and decryption
• AES key generation, encryption, and decryption
• Elliptic Curve Cryptography (ECC) for key generation, encryption, decryption, and digital signature operations
• HKDF for key derivation and encryption/decryption operations

Installation

To use EZ_WEB_CRYPTO in your project, simply import it:

import EZ_WEB_CRYPTO from 'ez-web-crypto';

Usage

Initialization

const ezWebCrypto = new EZ_WEB_CRYPTO();

Conversions

• Base64 to Uint8Array: ezWebCrypto.base64ToArray(base64String)
• Uint8Array to Base64: ezWebCrypto.arrayToBase64(arrayBuffer)

HMAC Generation

const hmac = await ezWebCrypto.HMAC(secret, data);

Data Hashing

const hash = await ezWebCrypto.HASH(algo, data, len);

Password-based Encryption and Decryption

• Encrypt: ezWebCrypto.PASSWORD_ENCRYPT(password, data)
• Decrypt: ezWebCrypto.PASSWORD_DECRYPT(password, encryptedData)

AES Operations

• Key Generation: ezWebCrypto.AESMakeKey(exportable)
• Key Import: ezWebCrypto.AESImportKey(key, exportable)
• Encryption: ezWebCrypto.AESEncrypt(key, data, nonce)
• Decryption: ezWebCrypto.AESDecrypt(key, nonce, data, returnText)

ECC Operations

• Key Generation: ezWebCrypto.EcMakeCryptKeys(exportable)
• Encryption: ezWebCrypto.EcEncrypt(privateKey, publicKey, data)
• Decryption: ezWebCrypto.EcDecrypt(privateKey, publicKey, nonce, data, returnText)
• Signature Generation: ezWebCrypto.EcMakeSigKeys(exportable)
• Data Signing: ezWebCrypto.EcSignData(privateKey, data)
• Signature Verification: ezWebCrypto.EcVerifySig(publicKey, signature, data)

HKDF Operations

• Encryption: ezWebCrypto.HKDFEncrypt(privateKey, publicKey, data)
• Decryption: ezWebCrypto.HKDFDecrypt(privateKey, publicKey, salt, iv, data, returnText)

Key Conversion Utilities

• ezWebCrypto.EcdhConvertKey(key)
• ezWebCrypto.EcdsaConvertKey(key)
