cscの作法 その218

概要

cscの作法、調べてみた。
BouncyCastle.dll使ってみた。
秘密鍵と証明書から、キーストア(p12)を作ってみた。

サンプルコード

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using Org.BouncyCastle.Asn1;
using Org.BouncyCastle.Asn1.X509;
using Org.BouncyCastle.Asn1.Pkcs;
using Org.BouncyCastle.Crypto;
using Org.BouncyCastle.Crypto.Generators;
using Org.BouncyCastle.Crypto.Operators;
using Org.BouncyCastle.Crypto.Parameters;
using Org.BouncyCastle.Crypto.Prng;
using Org.BouncyCastle.Math;
using Org.BouncyCastle.OpenSsl;
using Org.BouncyCastle.Pkcs;
using Org.BouncyCastle.Security;
using Org.BouncyCastle.X509;

namespace ConsoleExample
{
	class Program {
		static void Main(string[] args) {
			AsymmetricCipherKeyPair privateKey;
			Org.BouncyCastle.X509.X509Certificate readedCert;
			using (var reader = new StreamReader(@"privatekey.pem", Encoding.ASCII))
			{
				var pemReader = new PemReader(reader);
				privateKey = (AsymmetricCipherKeyPair) pemReader.ReadObject();
			}
			using (var reader = new StreamReader(@"certificate.crt", Encoding.ASCII))
			{
				var pemReader = new PemReader(reader);
				readedCert = (Org.BouncyCastle.X509.X509Certificate) pemReader.ReadObject();
			}
			var randGen = new CryptoApiRandomGenerator();
			var rand = new SecureRandom(randGen);
			var certEntry = new X509CertificateEntry(readedCert);
			var keyEntry = new AsymmetricKeyEntry(privateKey.Private);
			var p12 = new Pkcs12Store();
			p12.SetCertificateEntry("test16", certEntry);
			p12.SetKeyEntry("key", keyEntry, new X509CertificateEntry[] {
				certEntry
			});
			using (var stream = new FileStream(@"test16.p12", FileMode.Create))
			{
				p12.Save(stream, "password".ToCharArray(), rand);
				stream.Flush();
			}
			Console.WriteLine("OK");
		}
	}
}

以上。
