encrypting data

Hey guys,

cheers.

Use a secure server.

There are various encryption algorithms, but they are often slow running through server-side scripting. You can look up javascript encryption in a search engine to see what's already been developed. Encryption algorithms go from very simple and easy to crack to basically uncrackable in your lifetime.

The question to ask you is what you need to encrypt, and that way we can get an idea of what level of security is practical.

Use a secure server. That will encrypt data passing back and forth between the client and server. It's what it was designed for.

To use HTTPS you need to install a certificate on the web server.

This is not as hard as it sounds so you could do it yourself. Also many hosting sites offer this service.

Another option would be to use an ASP encryption plugin that will encrypt the data and pass it across a normal unprotected internet connection. This may hold advantages if you have a slower internet connection on the web server, but will require large amounts of processing by the server and therefore is only suitable to more computationally pwoerful machines.

An example of these encryption components would be ASPEncrypt which is available from persits Software.
