Disabling Browser Support for
the SSL3.0, TLS1, and TLS1.1 Protocols |
|
Depending on how your browser is configured, you may want to disable
SSL3.0, TLS 1.0, TLS 1.1, and enable TLS 1.2 (if these protocols are not
enabled by default). Note that older versions of Internet Explorer may not
have the TLS 1.1 and 1.2 protocols. |
Note that disabling browser support for the SSL3.0, TLS1, and TLS1.1
protocols may stop
you from connecting to sites that don’t support the TLS protocols.

III. Google Chrome:
How to Disable SSL3.0, TLS1, and TLS1.1 Protocols |
Google is currently testing a new version of Chrome in which the
SSL3.0, TLS1, and TLS1.1 protocols support has been removed. If you don’t want to
wait for that version to come out, you can use these instructions
to create a shortcut that allows you to open chrome with the SSL3.0,
TLS1, and TLS1.1
support turned off, until the next version of Chrome is released. |
Although these instructions and screenshots are for Google Chrome 38,
they will work for other versions of Chrome.
- Locate the Google Chrome shortcut; typically, this shortcut is
on your desktop.
If you don't have a Google Chrome shortcut, create one.
- Open the folder in which the Google Chrome application is
located.
For example:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Google Chrome
- In the Google Chrome folder, right-click on
the Google Chrome shortcut and then,
click Create shortcut.
- In the Shortcut window, click Yes to create a
shortcut on your desktop.
- Right-click on the Google Chrome shortcut and then,
click Properties.
- In the Google Chrome Properties window on
the Shortcut tab, in the Target field, add
the following line to the existing Target:
Add: --ssl-version-min=tls1.2
To: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
Make sure that you add a space between chrome.exe” and --ssl-version-min=tls1
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ssl-version-min=tls1
- Next, click Apply and then, click OK.
- From now on (until Google releases the version of Chrome
in which support fore the SSL3.0, TLS1, and TLS1.1 protocols
are removed), to
open Google Chrome, you must use this shortcut.
Whenever you use this shortcut to open Google Chrome, this
instance of the Google Chrome browser will not support the
SSL3.0, TLS1, and TLS1.1 protocols.
- You have successfully disabled the SSL3.0, TLS1, and TLS1.1
protocols in your Chrome browser.
