Just as a proof of concept I wrote a few lines to ensure that the public and private key could be loaded from xml. However, I'm struggling to make even the most simple stuff work on my machine: byte[] bytes = Encoding.UTF8.GetBytes("Some text"); bool fOAEP = true; // seeding a public and private key RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); var publicKey = rsa.ToXmlString(false); var privateKey = rsa.ToXmlString(true); //server side RSACryptoServiceProvider rsaServer = new RSACryptoServiceProvider(); rsaServer.FromXmlString(privateKey); var encrypted = rsaServer.Encrypt(bytes, fOAEP); //client side RSACryptoServiceProvider rsaClient = new RSACryptoServiceProvider(); rsaClient.FromXmlString(publicKey); var decrypted = rsaClient.Decrypt(encrypted, fOAEP); The last call to Decrypt throw a CryptographicException with the message "Error occurred while decoding OAEP padding.". I must be missing something totally obvious here. Do I need more setup of the rsa instances or maybe the initial rsa seeding instance? c# rsacryptoserviceprovider

The web service runs on a different PC than the console application. But I keep receiving the following exception message: Error occurred while decoding OAEP padding. When I run the encrypt and decrypt code on the same PC everything works just fine?!?! Both the web service and the console application makes use of the same KeyContainerName. Encryption Method: private static string EncryptString(string inputString, int dwKeySize, string keyContainerName) { // TODO: Add Proper Exception Handlers CspParameters cspParams = new CspParameters(); cspParams.KeyContainerName = keyContainerName; RSACryptoServiceProvider rsaCryptoServiceProvider = new RSACrypt
