TLS version Elektron Zero Daemon

Is there a way to configure which version of TLS the Elektron Zero Daemon is using for connections over the internet? I have EZD version 1.2.1.L1. By default it appears to be using TLS v1.0.

------------

Edit:

We are running on Linux, and the OpenSSL version that we have is: OpenSSL 1.0.1e-fips 11 Feb 2013

This is also the version listed in the EZD Install documentation. I believe this version should support TLSv1.2. However, when we run EZD it is defaulting to v1.0.

I get the following error in ezd.log:

Text: <Impl/ripcsslutils.c:932> ripc11SSLInitConnection error on SSL_connect SSL Error: 1 retVal: 0 errno: 0 93727:error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure:s3_pkt.c:1275:

When I just connect to the endpoints with the same version of openssl, it defaults to TLSv1.2 and returns the server certificate.

openssl s_client -connect amers1.streaming-ec.cp.thomsonreuters.com:443

    EZD 1.2 appears to be hardcoded to use TLSv1.0 (at least the Linux release). It appears to call "TLSv1_client_method(void)". The OpenSSL docs recommend using the general-purpose TLS_client_method(void) which allows the client/server to negotiate on the highest version supported by both client and server.

    We had to update to EZD 1.3 which does support TLSv1.2.
