What is webcrypto-core?

The webcrypto-core package is a JavaScript implementation of the Web Cryptography API specification. It provides a common interface for cryptographic operations such as hashing, signing, encryption, decryption, and key generation. This package is designed to be extensible, allowing for the addition of new cryptographic algorithms and their parameters.

What are webcrypto-core's main functionalities?

Hashing

This feature allows for the hashing of data using various algorithms. The code sample demonstrates how to hash a message using the SHA-256 algorithm.

const { Sha256 } = require('webcrypto-core');
let sha256 = new Sha256();
sha256.digest({name: 'SHA-256'}, Buffer.from('message')).then(digest => {
  console.log(digest);
});

Encryption/Decryption

This feature enables encryption and decryption of data. The code sample shows how to encrypt data using the AES-GCM algorithm.

const { AesGcm } = require('webcrypto-core');
let aesGcm = new AesGcm();
aesGcm.encrypt({name: 'AES-GCM', iv: Buffer.from(iv)}, key, Buffer.from(data)).then(encrypted => {
  console.log(encrypted);
});

Signing/Verification

This feature is used for signing data and verifying signatures. The code sample illustrates how to sign data using the RSA-PSS algorithm.

const { RsaPss } = require('webcrypto-core');
let rsaPss = new RsaPss();
rsaPss.sign({name: 'RSA-PSS', saltLength: 32}, privateKey, Buffer.from(data)).then(signature => {
  console.log(signature);
});
