OpenSSL

Overview

@superhero/openssl is a Node.js library that simplifies the creation and management of TLS certificates wrapping OpenSSL CLI as a child process. It provides an API to generate root, intermediate, end-entity and hybrid certificates, with configuration options for altered use cases. The library also supports verification of certificate chains at various levels of strength.

Installation

Install the package using npm:

npm install @superhero/openssl

Ensure that OpenSSL is installed and accessible in your system's PATH.

Features

• Generate self-signed, root, intermediate, and end-entity (leaf) certificates.
• Support for hybrid certificates.
• Flexible configuration for certificate parameters, including algorithms, extensions, and subject attributes.
• Verification of certificates with customizable strength levels.
• Password protection for private keys.
• DNS and IP restrictions for certificates.
• etc...

Usage

Basic Example

Create a self-signed hybrid certificate:

import OpenSSL from '@superhero/openssl';

const openssl = new OpenSSL();

const certificate = await openssl.hybrid();
console.log(certificate); // { cert, key, text, meta }

Generate a Root Certificate

const rootCA = await openssl.root();

Create an Intermediate CA

const intermediateCA = await openssl.intermediate(rootCA);

Generate an End-Entity Certificate

const leafCert = await openssl.leaf(intermediateCA, { dns: ['example.com'] });

Verify a Certificate Chain

const verified = await openssl.verify(leafCert, rootCA, intermediateCA);
console.log(`Verification status: ${verified}`);

Use Password-Protected Private Keys

const certificate = await openssl.hybrid({ password: 'password' });

Use an Alternative Algorithm

By default, the certificate generated will use algorithm: Ed25519.

const certificate = await openssl.hybrid({ algorithm: OpenSSL.ALGO.EdDSAEd448 });

Use an Alternative Hash

By default, the certificate generated will use hash: SHA256.

const certificate = await openssl.hybrid({ algorithm: OpenSSL.HASH.SHA512 });

Configuration

Config Object

The Config object allows detailed customization of certificates. Below are key properties:

• algorithm: Specify the algorithm (RSA:2048, ECDSA:P-256, etc.).
• hash: Define the hash algorithm (sha256, sha384, etc.).
• days: Validity period of the certificate.
• subject: Define subject attributes like CN, O, C, etc.
• dns: List of domain names for the certificate.
• ip: List of IP addresses for the certificate.
• password: Password for encrypting private keys.
• extensions: Add specific X.509 extensions like basicConstraints, subjectAltName, etc.

For full details, see the inline documentation in the source code.

Supported Algorithms

• RSA (2048, 4096 bits)
• ECDSA (P-256, P-384, P-521)
• EdDSA (Ed25519, Ed448)

Note

It's possible to alter the supported algorithms by simply adding to the OpenSSL.ALGO structure.

Supported Hashes

• SHA1
• SHA224
• SHA256
• SHA384
• SHA512

Note

It's possible to alter the supported hashes by simply adding to the OpenSSL.HASH structure.
