CryptoProtocolVersion

Property

CryptoProtocolVersion

Description

Specifies a comma-separated list of the protocol versions that can be used in creating an SSL connection to the data source. When multiple protocol versions are specified, the ADO.NET client will try the highest version first. If the highest version fails, the client will try the next highest version until the SSL handshake succeeds. Thus, the highest version supported by the runtime .NET Framework or operating system. If the runtime .NET Framework or operating system do not support the specified protocol(s), the connection fails and the connectivity service returns an error.

Note: TLS version 1.3 is supported in .NET Framework 4.8 and later versions, and in Windows 11 and Windows Server 2022.

Valid Values

TLS | TLS11 | TLS12 | TLS13

Default

TLS12,TLS13
