What are the advantages and disadvantages of HTTPS?

Answer 1

The benefit of HTTPS is that any sensitive information that need to be transferred for the user to another location can be done securely. And seeming this link is encrypted anyone who does try to intercept the message they have to get the code to decrypt it.

The disadvantages of HTTPS are not enough to tips the scales of good and bad, but if HTTPS is being used for a web request it is normally seemingly slower than http, also some older versions of browsers or SSL will refuse to work with HTTPS.
