The command should connect with TLS 1.1 or abort the connection if server advertises lower protocol version, same way it worked in 7.34.0 curl/libcurl versionĬurl 7.60.0 (x86_64-redhat-linux-gnu) libcurl/7.60.0 OpenSSL/1.1.0h zlib/1.2.11 libidn2/2.0.5 libpsl/0.20.2 (+libidn2/2.0.5) libssh/0.7.5/openssl/zlib nghttp2/1.32.0 In newest versions, the meaning of those options is, in practice, completely reversed - they specify the minimum version not the maximum version acceptable. For more information about dependencies for specific Configuration Manager features and scenarios, see About. TLS is a cryptographic security layer on top of TCP that makes the data tamper proof and guarantees server authenticity, based on strong public key. Ensure that TLS 1.2 is enabled as a protocol for SChannel at the operating system level. rootssclnx1 curl -k -1 -tlsv1.2 -user user:pass -X GET curl: option -tlsv1.2: is unknown curl: try 'curl -help' or 'curl -manual' for more information.

#TEST TLS 1.2 CONNECTIONS IN CURL UPDATE#

The behaviour of curl options changed radically between versions – in earlier releases (and even now with the -sslv3 option) using an option to specify exact protocol version meant 'use this version and this version only' – something that is necessary to support broken implementations that are TLS version intolerant. There are three tasks for enabling TLS 1.2 on clients: Update Windows and WinHTTP. If I try a curl command using tlsv1.2 option on System-1, it throws an error.
