I have done a google search on crypto topic.
Some examples are saying to CryptoStream(outStream,
TripleDESCryptoServiceProvider.CreateDecryptor(),CryptoStreamMode.Write) and then write chirp text into this stream. They are saying it will be decrypted. But this doesn't work for me. I used CryptoStream(inputStream,
TripleDESCryptoServiceProvider.CreateDecryptor(),CryptoStreamMode.Read) reads the chirp text and then writes into an output stream. That works!
