What is @types/node-forge?

@types/node-forge provides TypeScript type definitions for the node-forge library, which is a native implementation of TLS (and various other cryptographic tools) in JavaScript. It allows developers to perform a variety of cryptographic operations such as encryption, decryption, hashing, and digital signatures.

What are @types/node-forge's main functionalities?

Encryption and Decryption

This feature allows you to encrypt and decrypt data using the AES-CBC algorithm. The code sample demonstrates how to encrypt a simple 'Hello World' string and then decrypt it back to its original form.

const forge = require('node-forge');
const key = forge.random.getBytesSync(16);
const iv = forge.random.getBytesSync(16);
const cipher = forge.cipher.createCipher('AES-CBC', key);
cipher.start({iv: iv});
cipher.update(forge.util.createBuffer('Hello World'));
cipher.finish();
const encrypted = cipher.output;
const decipher = forge.cipher.createDecipher('AES-CBC', key);
decipher.start({iv: iv});
decipher.update(encrypted);
decipher.finish();
const decrypted = decipher.output.toString();
console.log(decrypted);

Hashing

This feature allows you to create cryptographic hashes using various algorithms like SHA-256. The code sample demonstrates how to hash a 'Hello World' string using SHA-256.

const forge = require('node-forge');
const md = forge.md.sha256.create();
md.update('Hello World', 'utf8');
const hash = md.digest().toHex();
console.log(hash);

Digital Signatures

This feature allows you to create and verify digital signatures. The code sample demonstrates how to sign a 'Hello World' string with a private key and then verify the signature with the corresponding public key.

const forge = require('node-forge');
const pki = forge.pki;
const keys = pki.rsa.generateKeyPair(2048);
const md = forge.md.sha256.create();
md.update('Hello World', 'utf8');
const signature = keys.privateKey.sign(md);
const verified = keys.publicKey.verify(md.digest().bytes(), signature);
console.log(verified);

TLS/SSL

This feature allows you to create and manage TLS/SSL certificates. The code sample demonstrates how to generate a self-signed certificate.

const forge = require('node-forge');
const pki = forge.pki;
const keys = pki.rsa.generateKeyPair(2048);
const cert = pki.createCertificate();
cert.publicKey = keys.publicKey;
cert.serialNumber = '01';
cert.validity.notBefore = new Date();
cert.validity.notAfter = new Date();
cert.validity.notAfter.setFullYear(cert.validity.notBefore.getFullYear() + 1);
const attrs = [{name: 'commonName', value: 'example.org'}];
cert.setSubject(attrs);
cert.setIssuer(attrs);
cert.sign(keys.privateKey);
const pem = pki.certificateToPem(cert);
console.log(pem);
