Package description

What is pvtsutils?

The pvtsutils npm package provides a set of utilities for working with binary data, particularly in the context of cryptographic operations. It includes functions for encoding and decoding data, converting between different data formats, and performing various binary manipulations.

What are pvtsutils's main functionalities?

Base64 Encoding/Decoding

This feature allows you to encode and decode strings to and from Base64 format, which is commonly used in data transmission and storage.

const pvtsutils = require('pvtsutils');

// Encoding a string to Base64
const base64Encoded = pvtsutils.Convert.ToBase64('Hello, World!');
console.log(base64Encoded); // Outputs: 'SGVsbG8sIFdvcmxkIQ=='

// Decoding a Base64 string
const base64Decoded = pvtsutils.Convert.FromBase64(base64Encoded);
console.log(base64Decoded); // Outputs: 'Hello, World!'

Hex Encoding/Decoding

This feature allows you to encode and decode strings to and from Hex format, which is useful for representing binary data in a human-readable form.

const pvtsutils = require('pvtsutils');

// Encoding a string to Hex
const hexEncoded = pvtsutils.Convert.ToHex('Hello, World!');
console.log(hexEncoded); // Outputs: '48656c6c6f2c20576f726c6421'

// Decoding a Hex string
const hexDecoded = pvtsutils.Convert.FromHex(hexEncoded);
console.log(hexDecoded); // Outputs: 'Hello, World!'

ArrayBuffer Conversion

This feature allows you to convert strings to ArrayBuffer and vice versa, which is useful for handling binary data in web applications.

const pvtsutils = require('pvtsutils');

// Converting a string to ArrayBuffer
const arrayBuffer = pvtsutils.Convert.FromUtf8String('Hello, World!');
console.log(arrayBuffer); // Outputs: ArrayBuffer { byteLength: 13 }

// Converting an ArrayBuffer to a string
const utf8String = pvtsutils.Convert.ToUtf8String(arrayBuffer);
console.log(utf8String); // Outputs: 'Hello, World!'

pvtsutils is a set of common utility functions used in various Peculiar Ventures TypeScript based projects.

Install

npm install pvtsutils

Using

const utils = require("pvtsutils");

The pvtsutils namespace will always be available globally and also supports AMD loaders.

Types

There is an index.d.ts file which makes easy to use current module as external

Helpers

Convert

Helps to convert string to ArrayBuffer and back

Convert support next encoding types hex, utf8, binary, base64, base64url. utf8 is default.

Examples

Converts string to buffer

const buf = Convert.FromString("some string", "hex");

Converts buffer to string

const str = Convert.ToString(buf, "utf8");

assign

Copies properties from objects to a target object. More info

Example
const obj = assign({}, {name: "Bob"}, {age: 12}); // {name: "Bob", age: 12}

isEqual

Returns true if 2 ArrayBuffers are equal

combine

Combines some ArrayBuffer values

Example
const buf1 = new Uint8Array([1, 2, 3]);
const buf2 = new Uint8Array([4, 5, 6]);
const buf = combine(buf1, buf2); // [1, 2, 3, 4, 5, 6]

Some example capabilities included in pvtsutils include:

  • Converting values to adn from hex,
  • Converting values to and from base64,
  • Working with base64 url,
  • Working with binary data.
  • And more...
