Advanced tools
Package description
The pvutils npm package provides a set of utility functions for working with ASN.1 and DER encoded data, commonly used in cryptographic applications. It simplifies the process of encoding and decoding data structures, making it easier to handle complex binary data formats.
Buffer Concatenation
This feature allows you to concatenate multiple ArrayBuffer objects into a single ArrayBuffer. It is useful when you need to combine binary data from different sources.
const pvutils = require('pvutils');
const buffer1 = new Uint8Array([1, 2, 3]);
const buffer2 = new Uint8Array([4, 5, 6]);
const concatenatedBuffer = pvutils.utilConcatBuf(buffer1.buffer, buffer2.buffer);
console.log(new Uint8Array(concatenatedBuffer));
String to ArrayBuffer Conversion
This feature converts a string into an ArrayBuffer, which is useful for encoding text data into a binary format.
const pvutils = require('pvutils');
const str = 'Hello, World!';
const arrayBuffer = pvutils.stringToArrayBuffer(str);
console.log(new Uint8Array(arrayBuffer));
ArrayBuffer to String Conversion
This feature converts an ArrayBuffer back into a string, which is useful for decoding binary data back into a readable text format.
const pvutils = require('pvutils');
const buffer = new Uint8Array([72, 101, 108, 108, 111]).buffer;
const str = pvutils.arrayBufferToString(buffer);
console.log(str);
Hexadecimal Encoding
This feature converts an ArrayBuffer into a hexadecimal string representation, which is useful for debugging and displaying binary data in a human-readable format.
const pvutils = require('pvutils');
const buffer = new Uint8Array([255, 0, 128]).buffer;
const hexString = pvutils.bufferToHexCodes(buffer);
console.log(hexString);
The asn1js package provides a comprehensive library for encoding and decoding ASN.1 data structures in JavaScript. It offers more advanced ASN.1 parsing and encoding capabilities compared to pvutils, making it suitable for more complex cryptographic applications.
The buffer package is a core Node.js module that provides a way to handle binary data directly in JavaScript. While it does not offer specific utilities for ASN.1 or DER encoding, it provides a robust set of methods for manipulating binary data, which can be used in conjunction with other libraries like pvutils.
The jsrsasign package is a comprehensive library for cryptographic operations in JavaScript, including ASN.1 encoding and decoding. It offers a broader range of cryptographic functionalities compared to pvutils, making it a more versatile choice for security-related applications.

Security News
The JavaScript community has launched the e18e initiative to improve ecosystem performance by cleaning up dependency trees, speeding up critical parts of the ecosystem, and documenting lighter alternatives to established tools.
Product
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.
