crypto-magic

crypto-magic

A set of utility functions/wrapper to simplify the development workflow

$ yarn add crypto-magic

Features

• Hash Function Wrapper (MD5, SHA1, SHA244, SHA256, SHA384, SHA512, WHIRLPOOL)
• Create Object/Array Hashes based on its JSON representation
• UUIDv4 generator usinc async crypto api randomBytes
• base64 urlsafe encoder/decoder

Hash Function Wrapper

Provides easy access to the Node.js Crypto Hash functions. Examples are available in examples/hash.js

const {hash} = require('crypto-magic');

console.log(hash.sha256('Hello World'));

Initialization

The argument encoding is optional and defines the output encoding of the digest.

• hex (default) - hexadecimal string output
• base64 - base64 string output
• base64urlsafe - url-safe base64 string output (/+= are replaced by _-)
• binary - binary output as Buffer

Hash Algorithms

The following wrappers are included:

• md5(input:mixed, [encoding:string])
• sha1(input:mixed, [encoding:string])
• sha2(input:mixed, [encoding:string])
• sha224(input:mixed, [encoding:string])
• sha256(input:mixed, [encoding:string])
• sha384(input:mixed, [encoding:string])
• sha512(input:mixed, [encoding:string])
• whirlpool(input:mixed, [encoding:string])

General Usage

const {hash} = require('crypto-magic');

// some input
const input = 'Hello World';

// display some hashes
console.log('Default HEX Output');
console.log(' |- MD5      ', hash.md5(input));
console.log(' |- SHA1     ', hash.sha1(input));
console.log(' |- SHA256   ', hash.sha256(input));
console.log(' |- SHA384   ', hash.sha384(input));
console.log(' |- SHA512   ', hash.sha512(input));
console.log(' |- WHIRLPOOL', hash.whirlpool(input));

// override the default output type
console.log('Override the default output settings');
console.log(' |- HEX      ', hash.sha1(input, 'hex'));
console.log(' |- BIN      ', hash.sha1(input, 'binary'));
console.log(' |- BASE64   ', hash.sha1(input, 'base64'));
console.log('');

Objects

Objects/Arrays are automatically serialized as JSON String. The JSON object is then passed into the hash function.

const {hash} = require('crypto-magic');

// demo object
const objectInput = {
    x: 1,
    b: 2,
    c: [5,6,7],
    d: {
        y: 'Hello',
        z: 'World'
    }
};

console.log('Object Input');
console.log(' |- SHA256   ', hash.sha256(objectInput));

Random Hash Generator

Create random hashes easily. Just calls the crypto-magic.hash functions with a random content generated by crypto-magic.random(514) - helpful for random URLs or filenames (e.g. cache hashes).

// url-safe base64
const {randomHash} = require('crypto-magic');

// all hash function of crypto-magic.hash are supported
console.log(await randomHash.sha256('base64urlsafe'));

// output like b7qhqd-WnKAH_GmBpSpvQrdkfUdLxL0m__XGcLTRsbI
