ssl – Enable TLS 1.0 using registry – Super User

Found a little gem:

I have found the way to enable TLS 1.0 in the client computer using registry using the method shown below.

Go to the registry location HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Add new DWORD named SecureProtocols and assign a value of 170 (decimal).

Checking all protocols (PCT1.0 + SSL2.0 + SSL3.0 + TLS1.0) present in the internet explorer will yield a new value of 170 .Value is based on the following calculation .

Ex: PCT1.0 + SSL2.0 + SSL3.0 + TLS1.02 + 8 + 32 + 128 = 170 Decimal or “aa” in Hex
