sha1

What is sha1?

The sha1 npm package is a simple utility for generating SHA-1 hashes. It is commonly used for creating unique identifiers, checksums, and for cryptographic purposes where SHA-1 is still considered acceptable.

What are sha1's main functionalities?

Generate SHA-1 Hash

This feature allows you to generate a SHA-1 hash from a given input string. The code sample demonstrates how to import the sha1 package, generate a hash from the string 'Hello, World!', and print the resulting hash.

const sha1 = require('sha1');
const hash = sha1('Hello, World!');
console.log(hash); // Output: '2ef7bde608ce5404e97d5f042f95f89f1c232871'

Hashing Buffers

This feature allows you to generate a SHA-1 hash from a Buffer object. The code sample demonstrates how to create a Buffer from the string 'Hello, World!', generate a hash from the buffer, and print the resulting hash.

const sha1 = require('sha1');
const buffer = Buffer.from('Hello, World!');
const hash = sha1(buffer);
console.log(hash); // Output: '2ef7bde608ce5404e97d5f042f95f89f1c232871'

Other packages similar to sha1

crypto

The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including a variety of hash algorithms like SHA-1, SHA-256, and more. It is more versatile and widely used compared to the sha1 package.

sha.js

The 'sha.js' package is a simple implementation of the SHA family of hash functions, including SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. It offers more options and flexibility compared to the sha1 package.

js-sha1

The 'js-sha1' package is a JavaScript implementation of the SHA-1 hash function. It is lightweight and can be used in both Node.js and browser environments, making it more versatile than the sha1 package.

README

sha1

a native js function for hashing messages with the SHA-1 algorithm

Installation

npm install sha1

or

ender build sha1

Example

var sha1 = require('sha1');

sha1("message");

This will return the string:

"6f9b9af3cd6e8b8a73c2cdced37fe9f59226e27d"

API

sha1(msg)

Returns the SHA-1 hash of the given message.

• msg String -- the message that you want to hash.

It's as simple as that.
