Security Through Obscurity Is Not A Good Principle. This example shows that legitimate certificates and domains can be used for phishing,.
This is an introduction to how to use cloud-based LDAP directory services. LDAP is a standard protocol for querying directory services for.
In this example we use host key verification in a virtual machine instance. We do this to illustrate that you can.
In this article we will explain how to check if a site is using secure SSL/TLS encryption with a simple perl command.
But if you really want to check if your website is using TLS, you should avoid doing this:
For example, lets assume that we have this host:
If you look at the headers, you will see that the HTTP version is HTTP/1.1, and the header tells you that the connection is encrypted.
This is not the behavior we wanted to see. The browser should not be able to decrypt the traffic!
How can we know if a site uses TLS? Lets see how to check a site using TLS:
First, we need to know the public key for the host.
This is the same as with SSH, we have to install the public key to the server.
To do this, we need to:

How to check a website with TLS with a Perl script?
There are 2 options:
Option 1: Connect to the site, download the certificate, compare the certificate, and if there is any mismatch, give up. This approach is likely to be difficult to automate.
Option 2: Connect to the site, using SSL verification, download the certificate, compare the certificate, and if there is any mismatch, give up.
