What is @stablelib/sha512?
@stablelib/sha512 is a JavaScript library that provides a secure and efficient implementation of the SHA-512 cryptographic hash function. It is part of the StableLib collection of cryptographic libraries, which are designed to be secure, fast, and easy to use.
What are @stablelib/sha512's main functionalities?
Hashing a string
This feature allows you to hash a string using the SHA-512 algorithm. The code sample demonstrates how to import the SHA512 class, create a new instance, update it with a message, and then generate the hash digest in hexadecimal format.
const { SHA512 } = require('@stablelib/sha512');
const message = 'Hello, world!';
const hash = new SHA512().update(message).digest();
console.log(Buffer.from(hash).toString('hex'));
Hashing a file
This feature allows you to hash the contents of a file using the SHA-512 algorithm. The code sample demonstrates how to create a read stream for a file, update the hash with each chunk of data, and then generate the hash digest in hexadecimal format once the stream ends.
const { SHA512 } = require('@stablelib/sha512');
const fs = require('fs');
const hash = new SHA512();
const stream = fs.createReadStream('path/to/file');
stream.on('data', (chunk) => hash.update(chunk));
stream.on('end', () => {
const digest = hash.digest();
console.log(Buffer.from(digest).toString('hex'));
});
Other packages similar to @stablelib/sha512
crypto
The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including the SHA-512 hash function. It is widely used and well-maintained, making it a reliable choice for cryptographic operations. Compared to @stablelib/sha512, the 'crypto' module is more versatile as it supports a wider range of cryptographic algorithms.
js-sha512
The 'js-sha512' package is a JavaScript implementation of the SHA-512 hash function. It is lightweight and easy to use, making it a good alternative to @stablelib/sha512 for projects that require only SHA-512 hashing. However, it may not be as optimized for performance as @stablelib/sha512.
hash.js
The 'hash.js' package is a collection of cryptographic hash functions, including SHA-512. It is part of the 'elliptic' library and is known for its performance and security. Compared to @stablelib/sha512, 'hash.js' offers a broader range of hash functions and is often used in conjunction with elliptic curve cryptography.
