I am developing a PHP application which collects information from a web based form & emails it to a recipient. The data is very sensitive so I am using a mod_ssl & will be getting a Verisign certificate before the site goes live.
The information is secure (I trust) between the browser & the server, but how can I ensure it stays secure as it is transmitted by email? Ideally I'd like the recipient to have a private key, then I could get PHP to encode it using the corresponding public key. Looking at the manual there seems to be a million ways to encrypt data - which is best?
