Isomorphic Cryptography Library for AES, HMAC and SHA2
This library supports AES, HMAC and SHA2 methods through native NodeJS and Browser APIs when available and fallbacks to vanilla javascript are already provided.
import * as isoCrypto from 'iso-crypto';
const length = 32;
const key = isoCrypto.randomBytes(length);
// key.length === length
import * as isoCrypto from 'iso-crypto';
import * as encUtils from 'enc-utils';
const key = isoCrypto.randomBytes(32);
const iv = isoCrypto.randomBytes(16);
const str = 'test message to encrypt';
const msg = encUtils.utf8ToArray(str);
const ciphertext = await isoCrypto.aesCbcEncrypt(iv, key, msg);
const decrypted = await isoCrypto.aesCbcDecrypt(iv, key, ciphertext);
// decrypted === str
import * as isoCrypto from 'iso-crypto';
import * as encUtils from 'enc-utils';

const iv = isoCrypto.randomBytes(16);
const macKey = encUtils.concatArrays(iv, key);
const dataToMac = encUtils.concatArrays(iv, key, msg);
const mac = await isoCrypto.hmacSha256Sign(macKey, dataToMac);
const result = await isoCrypto.hmacSha256Verify(macKey, dataToMac, mac);
// result will return true if match
import * as isoCrypto from 'iso-crypto';
import * as encUtils from 'enc-utils';
// SHA256
const str = 'test message to hash';
const msg = encUtils.utf8ToArray(str);
const hash = await isoCrypto.sha256(str);
// SHA512
const str = 'test message to hash';
const msg = encUtils.utf8ToArray(str);
const hash = await isoCrypto.sha512(str);
This library is intended for use in a Browser or NodeJS environment, however it is possible to use in a React-Native environment if NodeJS modules are polyfilled with react-native-crypto
