cscの作法 その221

概要

cscの作法、調べてみた。
秘密鍵pemファイルを、秘密鍵xmlファイルに変換してみた。

サンプルコード

pem2xml

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

	class test0 {
		static void Main() {
			AsymmetricCipherKeyPair privateKey;
			using (var reader = new StreamReader(@"privatekey.pem", Encoding.ASCII))
			{
				var pemReader = new PemReader(reader);
				privateKey = (AsymmetricCipherKeyPair) pemReader.ReadObject();
			}
			var rsaParams = DotNetUtilities.ToRSAParameters((RsaPrivateCrtKeyParameters) privateKey.Private);
			RSACryptoServiceProvider csp = new RSACryptoServiceProvider();
			csp.ImportParameters(rsaParams);
			File.WriteAllText("privatekey0.xml", csp.ToXmlString(true));
			Console.WriteLine("ok");
		}
	}

以上。
