In that case, you should explicitly set its value to 1. NET Framework 4.6.1 or earlier versions, the key defaults to 0. A value of 0 causes your app to use protocols picked by the. A value of 1 causes your app to allow the operating system to choose the protocol. The SystemDefaultTlsVersions registry key has a value of type DWORD. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\: SystemDefaultTlsVersions NET Framework 4.5.2 or earlier versions, the key defaults to 0. The strong cryptography uses more secure network protocols (TLS 1.2, TLS 1.1, and TLS 1.0) and blocks protocols that are not secure.

A value of 1 causes your app to use strong cryptography and a value of 0 disables strong cryptography. The SchUseStrongCrypto registry key has a value of type DWORD. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\: SchUseStrongCrypto NET Framework 4.5 to 4.5.2 the registry keys SchUseStrongCrypto and SystemDefaultTlsVersions will need to be set. NET Framework 4.6 to 4.6.2 the AppContext switches can be placed in the app.config or webconfig, as the system default will be set to a lower TLS or SSL Version.

Note that TLSv1 and TLSv1.1 are effectively deprecated as of 2020 you should avoid building new applications that rely on these protocols, and make every effort to upgrade applications that currently use them. SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 In your case you would want to use the following: = it's still possible to select which protocols your application supports by using the ServicePointManager class, specifically by setting the SecurityProtocol property to the relevant SecurityProtocolTypes.

NET Framework applications remain secure, the TLS version should not be hardcoded.NET Framework applications should use the TLS version the operating system (OS) supports. While Microsoft recommends against explicitly specifying protocol versions in favour of using the operating system's defaults: NET Framework 4.6 and higher: TLSv1, TLSv1.1, and TLS1.2 NET Framework 4.5.2: SSLv3, TLSv1, and TLSv1.1 NET Framework 4.5 and 4.5.1: SSLv3 and TLSv1 The default protocols enabled for the various framework versions are:
