Safely Transferring Information on the Internetby Nemp (Pilgrim)
|on Aug 06, 2002 at 13:08 UTC||Need Help??|
Nemp has asked for the wisdom of the Perl Monks concerning the following question:
I'm looking for a solution to transmit data as safely as possible over the internet - i.e. from my website server to anybody who accesses a 'members only' type area of my website.
From reading around on here it seems that without access to an https:// type server there is no way to prevent access to the data that you send over the net. (Please correct me if I'm wrong!)
Therefore, as far as I can tell, the only solution is to encrypt the data before sending it from the server and also encrypt the data at the client side before submitting any of it back to the server.
I'm very new to Perl (just finished taming the Llama, attempting to ride the Camel now) but I think I can easily enough write the server-side of such an encryption system. (I was thinking of using Crypt::OpenPGP) However I'm drawing a blank at the client side. I get the impression that anyone who lets me run client side perl from the web is either extremely trusting or stupid and so this doesn't seem a valid solution. Can anyone suggest to me how to accomplish the client side encryption of data before sending it on the web? Or at least point me in the right direction?
