Due to the nature of HTML and the inability to represent specific characters (ie NULL) in the ASCII table, you may run into a situation where you can encrypt your data, but decrypting it will not yield the original results. Don't be alarmed - the algorithm works. The problem is that it is not receiving the same encrypted characters that it originally returned. Try this. Take the key and the clear text message that you were trying to encrypt and do the following: <% Dim StrMyKey Dim StrMyMessage StrMyKey = "INSERT YOUR KEY HERE" StrMyMessage = "INSERT YOUR MESSAGE HERE" Response.Write(RC4(RC4(StrMyMessage, StrMyKey), StrMyKey)) %> This should return the original message that you were having problems decrypting the results. If you "must" display the results in the clients browser, then you may want to consider other alternatives of storing the information on the client. (Such as a hex format of the encrypted data in a hidden field) Hopefully this has helped answer any problems that you may run into.
