RSACryptoServiceProvider से एक X509Certificate2 बनाएं साथ विफल अनुरोध किया वस्तु

Question

नमूना कोड नहीं मिली:

 CspParameters cspParameters = new CspParameters(); 
     cspParameters.ProviderType = 1; // PROV_RSA_FULL 

     // Create the crypto service provider, generating a new 
     // key. 
     mRsaCSP = new RSACryptoServiceProvider(mDefaultKeyLength, cspParameters); 
     mRsaCSP.PersistKeyInCsp = true; 
     RSAParameters privateKey = mRsaCSP.ExportParameters(true); 


     byte[] rsaBytes = mRsaCSP.ExportCspBlob(true); 

     try 
     { 
      X509Certificate2 cert = new X509Certificate2(rsaBytes);     
      mKeyDataPfx = Convert.ToBase64String(cert.Export(X509ContentType.Pkcs12, password)); 
     } 
     catch (Exception ce) 
     { 
      string error = ce.Message; 
     }

यहाँ मेरी समाधान है, BouncyCastle लाइब्रेरी का उपयोग कर।

// create the RSA key from an XML string 
RSACryptoServiceProvider key = new RSACryptoServiceProvider(); 
key.FromXmlString(keyTextBox.Text); 

// convert to BouncyCastle key object 
var keypair = DotNetUtilities.GetRsaKeyPair(key); 

var gen = new X509V3CertificateGenerator(); 

string certName = Path.GetFileNameWithoutExtension(fileName); 
var name = new X509Name("CN=" + certName); 
var serial = BigInteger.ProbablePrime(120, new Random()); 

gen.SetSerialNumber(serial); 
gen.SetSubjectDN(name); 
gen.SetIssuerDN(name); 
gen.SetNotAfter(DateTime.Now.AddYears(10)); 
gen.SetNotBefore(DateTime.Now); 
gen.SetSignatureAlgorithm("MD5WithRSA"); 
gen.SetPublicKey(keypair.Public); 

// generate the certificate 
var newCert = gen.Generate(keypair.Private); 
// convert back to .NET certificate 
var cert = DotNetUtilities.ToX509Certificate(newCert); 
// export as byte array 
byte[] certData = cert.Export(X509ContentType.Pfx); 

File.WriteAllBytes(fileName, certData);
