I'm ever so gratified by your concise explanations of complicated terminologies.

Wanted to mention that there is yet another secured protocol in addition to the ones you explained so well.

This protocol is called SHTTP as opposed to HTTPS

The difference is that SHTTP is used for "Document Level Security", whereas HTTPS is "Communication Channel Level Security".

That means lesser overhead, because you only secure the message or document that you are sending this one time (SHTTP), than keeping the entire channel (or communication) secure all the time (HTTPS).

In HTTPS - HTTP sits over SSL, whereas in SHTTP, SSL sits over HTTP. Two schemes which are equally effective and both use Public key Encryption and Private Key Decryption, and both use RSA or DSA as the case maybe.

In my next post (with you permission) I would like to explain for your viewers in simple terms what "Public Key Encryption Really Means".

Warm Regards,
Sitanshu Ray
