Advanced tools
Package description
The buffer-equal npm package is a simple utility for checking if two Node.js Buffer or Uint8Array instances contain the same bytes. It is primarily used for comparing buffers in a way that is both efficient and straightforward.
Buffer Equality Check
This feature allows you to compare two buffers to determine if they are equal. It returns true if they are equal, false otherwise.
const bufferEqual = require('buffer-equal');
const buf1 = Buffer.from('hello world');
const buf2 = Buffer.from('hello world');
const buf3 = Buffer.from('goodbye');
console.log(bufferEqual(buf1, buf2)); // true
console.log(bufferEqual(buf1, buf3)); // falseThis package offers a similar functionality to buffer-equal. It provides a method to compare two Node.js Buffer or Uint8Array objects for equality. The difference is mainly in the implementation and possibly in performance characteristics.
Similar to buffer-equal, this package is used to check if two buffers are equal. It focuses on providing a safe comparison that doesn't leak timing information, which can be important for preventing timing attacks in cryptographic operations.
Readme
Return whether two buffers are equal.
var bufferEqual = require('buffer-equal');
console.dir(bufferEqual(
new Buffer([253,254,255]),
new Buffer([253,254,255])
));
console.dir(bufferEqual(
new Buffer('abc'),
new Buffer('abcd')
));
console.dir(bufferEqual(
new Buffer('abc'),
'abc'
));
output:
true
false
undefined
var bufferEqual = require('buffer-equal');
Return whether the two buffers a and b are equal.
If a or b is not a buffer, return undefined.
With npm do:
npm install buffer-equal
