## Features

### Current features

- 100% TypeScript and ESM

- Zero-copy reading and writing

- No external dependency

- No cryptography

- Rust-like patterns

- Zero-copy PEM <=> DER <=> ASN1 <=> X509 reading and writing

- X.509 certificates (v3)

- X.501 encoding and decoding

### [Upcoming features](https://github.com/sponsors/hazae41)

- X.509 extensions (v3)

## Usage

### Reading DER

```typescript

import { Certificate, X509 } from "@hazae41/x509";

const bytes = await readFile("./cert.der")

const cert = X509.tryReadFromBytes(bytes, Certificate).unwrap()

```

### Reading PEM

```typescript

import { PEM, Certificate, X509 } from "@hazae41/x509";

const bytes = PEM.tryParse(await readFile("./cert.pem", "utf8")).unwrap()

const cert = X509.tryReadFromBytes(bytes, Certificate).unwrap()

```
