I want to use RSACryptoServiceProvider to encrypt/decrypt ASP.NET server text
box for credit card information.  The problem is that I have to encrypt the
text in textbox, which user input (i.e. credit card #) before it post to
server to insure the security of the data transformation.  However any server
events, i.e., button click event are already after the posted back to the
server through internet.  Please advice how I can encrypt data before
postback ( It should be easy to decrypt data in any server event, i.e.,
button click event).
Thanks,
