buffer-xor
Advanced tools
Package description
The buffer-xor npm package is a utility that allows for the bitwise XOR operation to be performed on two buffers. This operation is useful in various cryptographic functions and data manipulation tasks where you need to combine data in a way that preserves or manipulates information in a reversible manner.
Bitwise XOR operation on buffers
This feature allows you to perform a bitwise XOR operation on two buffers. The code sample demonstrates how to use the buffer-xor package to XOR two hexadecimal buffers and print the result. This is particularly useful in cryptographic operations where XOR is a common operation.
"use strict";\nconst xor = require('buffer-xor');\nlet a = Buffer.from('f00d', 'hex');\nlet b = Buffer.from('dead', 'hex');\nlet output = xor(a, b);\nconsole.log(output.toString('hex')); // Output will be '2f73'While not directly offering XOR functionality, the 'buffer' package in Node.js can be used in conjunction with custom code to perform similar operations. It provides a way to handle binary data directly with buffers, but you would need to implement the XOR logic manually.
Crypto-js is a collection of cryptographic algorithms implemented in JavaScript, including various operations that can be performed on buffers. While it is more comprehensive and includes a wide range of cryptographic functions beyond XOR, it can be used for similar purposes when working with encryption and data manipulation.
Readme
A simple module for bitwise-xor on buffers.
var xor = require('buffer-xor')
var a = new Buffer('00ff0f', 'hex')
var b = new Buffer('f0f0', 'hex')
console.log(xor(a, b))
// => <Buffer f0 0f 0f>
Or for those seeking those few extra cycles, perform the operation in place with
xorInplace:
NOTE: xorInplace won't xor past the bounds of the buffer it mutates so make
sure it is long enough!
var xorInplace = require('buffer-xor/inplace')
var a = new Buffer('00ff0f', 'hex')
var b = new Buffer('f0f0', 'hex')
console.log(xorInplace(a, b))
// => <Buffer f0 0f 0f>
// See that a has been mutated
console.log(a)
// => <Buffer f0 0f 0f>
