I use RSACryptoServiceProvider in my C# code, and it's working good I could Export RSA XML private and public keys, but for some reason I need to convert this key to *.pem with format (PKCS8 Unencrypted) my private key like <RSAKeyValue> <Modulus>zYs6baSaRDgLc5fG3/ozwGwS8OAvxd9quE2su+7//Lnz2WuIbe8jMc5kL7p2gsPZUEoB88SFHdGZSYiZJhERDc/1iQ4VsW2/ra8DBW+1m3K33EDvvI3rJ0NIyuRNuwoYql3hYdY0cdW6Gru9ZARCpptgBSJEiUSPjlzDEXz3RaU=</Modulus> <Exponent>AQAB</Exponent> <P>89aDVrzNZuDfkCCUR6LKlxHul64zb4EBUN4vr6VZ4LrjEqT6m7+a/8lIrgSK03R1hDdOzeg79eS0OLH5cbe6xQ==</P> <Q>18vAJpkwmhDSMjcPAE/4LufpZ6ukaOgkcPj9LngZSQlIt

I need to encrypt String for project related purpose and was given the below code for the same by vendor. public static string EncryptString(string StringToEncrypt) { RSACryptoServiceProvider provider = new RSACryptoServiceProvider(); string xmlString = "<RSAKeyValue><Modulus>qqoWhMwGrrEBRr92VYud3j+iIEm7652Fs20HvNckH3tRDJIL465TLy7Cil8VYxJre69zwny1aUAPYItybg5pSbSORmP+hMp6Jhs+mg3qRPvHfNIl23zynb4kAi4Mx/yEkGwsa6L946lZKY8f9UjDkLJY7yXevMML1LT+h/a0a38=</Modulus><Exponent>AQAB</Exponent><P>20PwC7nSsfrfA9pzwSOnRYdbhOYivFSuERxvXHvNjCll5XdmFYYp1d2evXcXbyj3E1k8azce1avQ9njH85NMNQ==</P><Q

any body can explain the parameters of RSAParameters i had seen the parameters like p,d,e,q,... i need the private key and public key from it i got the link http://msdn.microsoft.com/en-us/library/system.security.cryptography.rsaparameters%28v=vs.90%29.aspx[^] i am using the sample code as like this can anybody can say it was right or not sample code: //Generate a public/private key pair. RSACryptoServiceProvider RSA = new RSACryptoServiceProvider(); //Save the public key information to an RSAParameters structure. RSAParameters RSAKeyInfo = RSA.ExportParameters(true); //public key TextBox5

I've used the .NET class RSACryptoServiceProvider to get a keypair: using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider()) { File.WriteAllText ("PublicKeyOnly.xml", rsa.ToXmlString (false)); File.WriteAllText ("PublicPrivate.xml", rsa.ToXmlString (true)); } Now, I would like to use this with openSSH, but the key format looks nothing alike. Does anyone know how to convert both the public and private keys to files that openSSH can use? Thanks! I really needed to achieve Openssl interoperability with RSACryptoServiceProvider, so that I could implement a software licence key system

I wrote a code block for Encrypt/Decrypt Streams. The code is working in my local machine. But when I publish my code on web The Decryption functions throws "Bad Data" exception Here is the my Encrypton and Decryption functions private static MemoryStream EncryptStream(XmlDocument xmlDoc, XmlElement elementToEncrypt, string password) { CspParameters cspParams = new CspParameters(); cspParams.KeyContainerName = password; RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider(cspParams); RijndaelManaged sessionKey = null; try { if (xmlDoc == null) throw new ArgumentNullException("xmlDoc"

I've been developing an ASP.NET site on an older machine running XP home. I recently got a new Win 7 PC and moved all my project files across. When I try and run the project, I get this error message: "Failed to decrypt using provider 'MyRsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened." I realised that I encrypted parts of my web.config file using a RSA encryption . This is where the problem now lies. I'm not sure how to get that key working again so that I can use it on my new machine. I exported the key from the older machine and

I need to export private key from Windows store. What should I do if the key is marked as non-exportable? I know that it is possible, program jailbreak can export this key. To export key I use Org.BouncyCastle.Security.DotNetUtilities.GetKeyPair() that exports key from (RSACryptoServiceProvider)cryptoProv.ExportParameters(true) . Exported key I use in Org.BouncyCastle.Cms.CmsSignedDataGenerator for CMS signature. I need solution for .Net, but any solution will be useful. Thank you. Gentil Kiwi You're right, no API at all that I'm aware to export PrivateKey marked as non-exportable. But if you

I'm trying to initialize RSACryptoServiceProvider with my own public and private keys. As far as I could research, the way to do this is to call the constructor with RSACryptoServiceProvider RSAalg = new RSACryptoServiceProvider(cspParams); cspParams as shown above. However, when I look at the msdn example on the use of it: http://msdn.microsoft.com/en-us/library/ca5htw4f.aspx I don't see any place where they set the private or public keys. Only using a KeyContainer. When I create an RSACryptoServiceProvider without a cspParam, then it is by default set to only use a Public key. I notice this
