minimalistic-crypto-utils

What is minimalistic-crypto-utils?

The minimalistic-crypto-utils package provides utility functions for cryptographic operations. These utilities are designed to be small and efficient, making them suitable for environments where minimal overhead is desired.

What are minimalistic-crypto-utils's main functionalities?

Bytes to Hex String Conversion

Converts a byte array to a hexadecimal string representation.

"use strict";
const utils = require('minimalistic-crypto-utils');
const bytes = new Uint8Array([72, 101, 108, 108, 111]);
const hexString = utils.toHex(bytes);
console.log(hexString); // Outputs: '48656c6c6f'

Hex String to Bytes Conversion

Converts a hexadecimal string to a byte array.

"use strict";
const utils = require('minimalistic-crypto-utils');
const hexString = '48656c6c6f';
const bytes = utils.toArray(hexString);
console.log(bytes); // Outputs: [72, 101, 108, 108, 111]

Concatenation of Byte Arrays

Concatenates multiple byte arrays into one.

"use strict";
const utils = require('minimalistic-crypto-utils');
const arr1 = new Uint8Array([72, 101]);
const arr2 = new Uint8Array([108, 108, 111]);
const combined = utils.concat(arr1, arr2);
console.log(combined); // Outputs: Uint8Array [72, 101, 108, 108, 111]

Equality Check for Byte Arrays

Checks if two byte arrays are equal.

"use strict";
const utils = require('minimalistic-crypto-utils');
const arr1 = new Uint8Array([72, 101, 108, 108, 111]);
const arr2 = new Uint8Array([72, 101, 108, 108, 111]);
const isEqual = utils.equals(arr1, arr2);
console.log(isEqual); // Outputs: true

Other packages similar to minimalistic-crypto-utils

crypto-js

Crypto-js is a package with more comprehensive cryptographic functionalities including various encryption standards, hashing functions, and encoding utilities. It is larger and more feature-rich compared to minimalistic-crypto-utils.

buffer

The buffer package provides Node.js Buffer class utilities which can be used for handling binary data. It offers a similar byte array manipulation functionality but is a core part of Node.js and not specifically focused on cryptographic utilities.

node-forge

Node-forge is a JavaScript implementation of various networking and cryptography tools. It is much more extensive than minimalistic-crypto-utils, offering a wide range of cryptographic operations including certificate management, TLS, and various encryption algorithms.

Very minimal utils that are required in order to write reasonable JS-only crypto module.

Usage

const utils = require('minimalistic-crypto-utils');

utils.toArray('abcd', 'hex');
utils.encode([ 1, 2, 3, 4 ], 'hex');
utils.toHex([ 1, 2, 3, 4 ]);
