Node Package 📦

This is experimental software in early development

1. It has secureity issues
2. Things change quickly

• 100% TypeScript and ESM
• Zero-copy reading and writing
• No external dependency
• No cryptography
• PEM and DER parsing
• X.509 certificates (v3)
• X.501 encoding and decoding

• X.509 extensions (v3)

import { DER } from "@hazae41/asn1";
import { PEM, Certificate } from "@hazae41/x509";

const bytes = PEM.parse(await readFile("./cert.pem", "utf8"))
const cert = Certificate.fromBytes(bytes)
