Counting bytes passed in streams written to by StreamWriter.

Hi,

Is there a stream implementation or ICryptoTransform implementation similar to the md5 which simply counts bytes rather than calculates a hash.

I am writing text to an encrypted file and need to know the md5 and size of the raw unencrypted byte data. I've seen code for calculating md5 of a stream, but need one which simply counts bytes.

Something like this

// File Stream
FileStream fileStream = this.fileInfo.Open(FileMode.CreateNew, FileAccess.Write, FileShare.None);'

// Encrypter wraps File Stream
CryptoStream cryptoStream = encrypter.BuildEncodingStream(fileStream);

// Md5 wraps Encryption
CrytpStream md5Stream = = new CryptoStream(cryptoStream, md5, CryptoStreamMode.Write);

// StreamWriter wraps md5Stream
StreamWriter sw = new StreamWriter(md5Stream);

// Need to wrap md5 in 'byte counter'

// write text
sw.writeLine("text");
sw.close();

// now have md5
string md5Val = md5.Hash;

// need length
long size =

Thanks.

Cheers,

Phillip
