How to identify the Cipher used by an HTTPS Connection

HTTPS is a secure version of HTTP. When making a connection using HTTPS, either SSL or TLS will be used to encrypt the information being sent to and from the server. This encryption makes it very difficult for a third party to read the data packets. The information is encrypted using a Cipher or encryption key, the type of Cipher used depends on the Cipher Suite installed and the preferences of the server. 

This article describes how to find the Cipher used by an HTTPS connection, by using Internet Explorer, Chrome or FireFox, to read the certificate information.

HTTPS | TLS | SSL

Instructions

Using a browser to open an HTTPS page and check the certificate properties to find the type of Cipher used to encrypt the connection.

  2. Enter the URL you wish to check in the browser.
  3. Right-click the page or select the Page drop-down menu, and select Properties.

How to find the Cipher in Chrome

  1. Launch Chrome.
  2. Enter the URL you wish to check in the browser.
  3. In the address bar, click the icon to the left of the URL.
  4. Look for the line "The connection uses...". This will describe the version of TLS or SSL used.

How to find the Cipher in FireFox
