Introducing Enhanced Alert Actions and Triage Functionality
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.

Package description
The scmp package in npm is a secure, constant-time comparison of strings or buffers. It is primarily used to prevent timing attacks when comparing sensitive data, such as cryptographic hashes or tokens.
Secure String Comparison
This feature allows for the secure comparison of two strings, ensuring that the time taken to compare is constant, thus preventing timing attacks.
const scmp = require('scmp');
const a = 'not_so_secret';
const b = 'not_so_secret';
console.log(scmp(a, b)); // outputs: true
Secure Buffer Comparison
Similar to string comparison, this feature enables the secure, constant-time comparison of two buffers, which is useful for comparing binary data securely.
const scmp = require('scmp');
const buffer1 = Buffer.from('secret_data');
const buffer2 = Buffer.from('secret_data');
console.log(scmp(buffer1, buffer2)); // outputs: true
bcryptjs is a package that provides secure password hashing. While it does not offer direct string comparison like scmp, it is used for securely handling passwords which is a similar domain of security.
The built-in Node.js 'crypto' module provides a method called 'timingSafeEqual' which performs a constant-time comparison of buffers, similar to what scmp does. It is a more comprehensive security toolkit that includes a variety of cryptographic functions.
Readme
Safe, constant-time comparison of strings.
npm install scmp
To minimize vulnerability against timing attacks.
var scmp = require('scmp');
var hash = 'e727d1464ae12436e899a726da5b2f11d8381b26';
var givenHash = 'e727e1b80e448a213b392049888111e1779a52db';
if (scmp(hash, givenHash)) {
console.log('good hash');
} else {
console.log('bad hash');
}
