sha

What is sha?

The 'sha' npm package is used for generating SHA (Secure Hash Algorithm) hashes. It supports various SHA algorithms like SHA-1, SHA-256, SHA-384, and SHA-512. This package is useful for creating cryptographic hashes of data, which can be used for data integrity checks, password hashing, and more.

What are sha's main functionalities?

Generate SHA-1 Hash

This feature allows you to generate a SHA-1 hash of a given input string. The code sample demonstrates how to create a SHA-1 hash of the string 'Hello World' and output it in hexadecimal format.

const sha = require('sha');
const hash = sha('sha1').update('Hello World').digest('hex');
console.log(hash);

Generate SHA-256 Hash

This feature allows you to generate a SHA-256 hash of a given input string. The code sample demonstrates how to create a SHA-256 hash of the string 'Hello World' and output it in hexadecimal format.

const sha = require('sha');
const hash = sha('sha256').update('Hello World').digest('hex');
console.log(hash);

Generate SHA-384 Hash

This feature allows you to generate a SHA-384 hash of a given input string. The code sample demonstrates how to create a SHA-384 hash of the string 'Hello World' and output it in hexadecimal format.

const sha = require('sha');
const hash = sha('sha384').update('Hello World').digest('hex');
console.log(hash);

Generate SHA-512 Hash

This feature allows you to generate a SHA-512 hash of a given input string. The code sample demonstrates how to create a SHA-512 hash of the string 'Hello World' and output it in hexadecimal format.

const sha = require('sha');
const hash = sha('sha512').update('Hello World').digest('hex');
console.log(hash);

Other packages similar to sha

crypto

The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. It is more comprehensive and versatile compared to 'sha', supporting a wider range of cryptographic operations.

hash.js

The 'hash.js' package is a JavaScript library that provides a simple way to create hash digests of data. It supports various hash algorithms including SHA-1, SHA-256, SHA-384, and SHA-512. It is similar to 'sha' but offers a more modular approach and additional features like HMAC.

js-sha256

The 'js-sha256' package is a JavaScript implementation of the SHA-256 hash function. It is lightweight and fast, making it suitable for client-side applications. Unlike 'sha', it focuses solely on SHA-256, providing a highly optimized implementation for this specific algorithm.

README

sha

Check and get file hashes (using any algorithm)

Installation

$ npm install sha

API

check(fileName, expected, [options,] cb)

Asynchronously check that fileName has a "hash" of expected. The callback will be called with either null or an error (indicating that they did not match).

Options:

• algorithm: defaults to sha1 and can be any of the algorithms supported by crypto.createHash

get(fileName, [options,] cb)

Asynchronously get the "hash" of fileName. The callback will be called with an optional error object and the (lower cased) hex digest of the hash.

Options:

• algorithm: defaults to sha1 and can be any of the algorithms supported by crypto.createHash
