tsse

⏱ Constant time string/buffer equals.
_{Coded with ❤️ by Simone Primarosa.}

Synopsis

tsse is a string comparison algorithm to prevent Node.js timing attacks.

This differs from crypto.timingSafeEqual because it:

supports both strings and Buffers;

supports inputs of different lengths.

Install

$ npm install --save tsse

Usage

1const tsse = require('tsse');
2
3const hash      = '0a4d55a8d778e5022fab701977c5d840bbc486d0';
4const givenHash = '1265a5eb08997ced279d3854629cba68a378b528';
5
6if (tsse(hash, givenHash)) {
7  console.log('good hash');
8} else {
9  console.log('bad hash');
10}
11// => bad hash

API

tsse(hiddenStr, inputStr) ⇒ `boolean`

Does a constant-time String comparison.
NOTE: When hiddenStr and inputStr have different lengths hiddenStr is compared to itself, which makes the comparison non-commutative (time-wise).

Kind: global function
Returns: boolean - true if equals, false otherwise.
Access: public

Param	Type	Description
hiddenStr	`string` \| `Buffer`	A string that you don't want to leak.
inputStr	`string` \| `Buffer`	Another string.
