The behaviour in 7.34.0 was also consistent with the behaviour of -tls1_0, -tls1_1, -tls1_2 and (now) -tls1_3 option in both OpenSSL s_client and s_server. Option 2 requires server adjustments, which we know can be. Two options are provided: You connect with us using TLS 1.2 protocol. This means you will have to make a few adjustments in your integration.

For more information about dependencies for specific Configuration Manager features and scenarios, see About. Due to PCI-DSS compliance, from March 1st 2018, the UOL BoaCompra postback endpoint will start to accept only TLS 1.2 connections. Ensure that TLS 1.2 is enabled as a protocol for SChannel at the operating system level.

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 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. In newest versions, the meaning of those options is, in practice, completely reversed - they specify the minimum version not the maximum version acceptable. 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.
