Hello,

I am trying to use the RSACryptoServiceProvider to encrypt/decrypt. Encrypting works fine, but the Decrypt method() throws an exception with the message: Unknown Error '80007005'.

This is the code:

Byte[] plainData = encoding.GetBytes(plainText); Byte[] encryptedData; RSAParameters rsap1; Byte[] decryptedData; using (RSACryptoServiceProvider rsa1 = new RSACryptoServiceProvider()) { encryptedData = rsa1.Encrypt(plainData, false); rsap1 = rsa1.ExportParameters(false); }

using (RSACryptoServiceProvider rsa2 = new RSACryptoServiceProvider()) { rsa2.ImportParameters(rsap1); decryptedData = rsa2.Decrypt(encryptedData, false); }

decryptedText = encoding.GetString(decryptedData, 0, decryptedData.Length);

Is anyone aware of a workaround?

Thanks!
