Transport Layer Security (TLS) encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence.

Click on “Preferences” and then click on the “Advanced” icon. Then click on the “Change Settings…” button. Click on the “Advanced” tab in the Internet Properties window and browse through the Settings section to make sure that the TLS checkbox is selected. Check the box if it is not and then click on the “OK” button.
Click on: Start -> Control Panel -> Internet Options 2. Click on the Advanced tab 3. Scroll to the bottom and check the TLS version described in steps 3 and 4: 4. If Use SSL 2.0 is enabled, you must have TLS 1.2 enabled (checked) 5.

To disable the TLS 1.1 protocol, create an Enabled entry in the appropriate subkey. This entry does not exist in the registry by default. After you have created the entry, change the DWORD value to 0. To enable the protocol, change the DWORD value to 1.
Right-click on Client, select New > DWORD (32-bit) Value, and name it “Enabled”. Now, since the default value of Enabled is 0, TLS 1.0 will be disabled. However, if you want to enable the protocol, just change the Value data to 1. This way, you have disabled TLS 1.0 on your computer.
Enter the URL you wish to check in the browser. Right-click the page or select the Page drop-down menu, and select Properties. In the new window, look for the Connection section. This will describe the version of TLS or SSL used.
How to check if TLS 1.2 is enabled? If the registry key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2ClientDisabledByDefault is present, the value should be 0.
- Go to ‘Tools’ or click the settings icon:
- Select ‘Internet Options’ > ‘Advanced tab’.
- Scroll down to the ‘Security’ section at the bottom.
- Make sure ‘TLS 1.1’ and ‘TLS 1.2’ are checked.
- Make sure all other TLS 1.0 and all SSL protocols are disabled.
What is the difference between TLS 1.3 and TLS 1.2? TLS 1.3 is the latest version of the TLS protocol. TLS, which is used by HTTPS and other network protocols for encryption, is the modern version of SSL.
TLS refers to Transport Layer Security, and it is a cryptographic protocol that provides authentication, data integrity, privacy as well as end-to-end communications between two devices connected over a network.
iOS, iPadOS, and macOS support Transport Layer Security (TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3) and Datagram Transport Layer Security (DTLS). The TLS protocol supports both AES128 and AES256, and prefers cipher suites with forward secrecy.
Press Ctrl+F12 (or Command+F12 on a Mac), or click the Opera menu and go to Settings→Preferences. Click on the Advanced tab, then Security in the left sidebar, then the Security Protocols button. Make sure that only Enable TLS 1.2 is checked.
Click the gear icon (Tools menu), then select Internet Options. Select the Advanced tab. Scroll to the Security section, then check Use TLS 1.2. Click OK, then close Internet Explorer.
To enable the TLS 1.0 protocol, create an Enabled entry (in the Client or Server subkey) and change the value to 1 . To disable it, change the DWORD value to 0 . To disable TLS 1.0 by default, create a DisabledByDefault entry and change the value to 1 .

The usual cause for the problem is your antivirus unnecessarily scanning the sites’ certificates which slows down the process of requesting files from the servers which, in effect, can cause the “Performing a TLS Handshake” message to hang for a long time in Mozilla Firefox.
This is an integer from 1 to 600 that specifies the number of seconds to wait for the secure handshake to be initiated and to complete. If the timer expires before the handshake has been initiated, the TCP connection is reset. The default is 10 seconds.
A TLS handshake is the process that kicks off a communication session that uses TLS encryption. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the encryption algorithms they will use, and agree on session keys.
