SharpAESCrypt.CanRead becomes false after reading to end

[abcjjy]

I'm trying to make it work with GZipStream, which requires CanRead be true while reading.

I looked through the code. m_cryptDataStream is closed in Read() when reading to the end. And then, m_cryptDataStream.CanRead becomes false and SharpAESCrypt.CanRead returns false. If Crypto.Closed() is not called, CanRead will stay true.

As far as I know, Streams are usually disposed in Dispose(). Why do you close it in Read()? Is there any other consideration? I tried to commented out the Close() line. It seems work fine as well. But I'm not sure if it is safe or not.
