x509csr 1.0.2

Create X.509 Certificate Signing Requests, plus associated PEM helper functions.

Make X.509 RSA Certificate Signing Requests (CSR). We include helper functions for generating Keypairs and outputting associated PEMs.

This is moderately barebones, contributions welcome.

The CSR PEM can be verified using

openssl req -text -noout -verify -in csr.pem

Usage

A simple usage example:

import "package:x509csr/x509csr.dart";

import "package:pointycastle/export.dart";
import 'package:asn1lib/asn1lib.dart';

main(List<String> arguments) {
  AsymmetricKeyPair keyPair = rsaGenerateKeyPair();

  ASN1ObjectIdentifier.registerFrequentNames();
  Map<String, String> dn = {
    "CN": "www.davidjanes.com",
    "O": "Consensas",
    "L": "Toronto",
    "ST": "Ontario",
    "C": "CA",
  };

  ASN1Object encodedCSR = makeRSACSR(dn, keyPair.privateKey, keyPair.publicKey);

  print(encodeCSRToPem(encodedCSR));
  print(encodeRSAPublicKeyToPem(keyPair.publicKey));
  print(encodeRSAPrivateKeyToPem(keyPair.privateKey));
}
