Hello,

When i decrypt data using TripleDESCryptoServiceProvider, it throws
"System.Security.Cryptography.CryptographicException: Bad Data." error

Sounds like either your encryption and decryption settings are not exactly
the same, or you are not properly closing/flushing the encryption stream.
Closing the CryptoStream is important because otherwise all of the encrypted
data is not actually written to the output file.

Here's an example of using TripleDESCryptoServiceProvider:

Try if the above code works for you, and if so, then check to see what's
different in your own code.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.
