What is the difference between HTTPS and HTTP?
https (‘s’ indicating ‘secure) would be the higher level of security, and indicates that some method of signing a certificate (Verisign for example) was used to authenticate who the site says it is, and a few other verification steps. When available for a site, it merely indicates that traffic goes to who is indicated in the address bar (encrypted) so no one else can ‘read’ or intercept it. In essence, it indicates a method of communication: nothing else. It does not give any indication of reliability, trustworthiness, internal security, or anything else about any particular business. That you must do on your own. Note that even SSL/TLS secure communication has it’s weaknesses and known vulnerabilities, and is not an absolute state of affairs over the Internet.
