Got encryption working in .NETCF thanks to the help of the OpenNETCF guys. This post is really meant for my own reference so that I can list the sites that had the info I needed:

• The OpenNETCF.Security.Cryptography works almost the same as the real .NET one
• MSDN site detailing System.Security.Cryptography
• Tiny Encryption Algorithm showing me how to convert Bytes< ->String :-)

In the end all of that adds up to this:

    byte[] encryptedData;
    byte[] decryptedData;
    byte[] dataBytes = System.Text.ASCIIEncoding.ASCII.GetBytes("hello");

    //Encrypt
    RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
    encryptedData = rsa.EncryptValue(dataBytes);

    //Decrypt
    decryptedData = rsa.DecryptValue(encryptedData);
    MessageBox.Show("Encrypted Data : " + System.Text.ASCIIEncoding.ASCII.GetString(encryptedData, 0, encryptedData.Length));
    MessageBox.Show("Decrypted Data : " + System.Text.ASCIIEncoding.ASCII.GetString(decryptedData, 0, decryptedData.Length));

which encrypts the string "Hello" and then decrypts it again!
