![]() ![]() Have a command line application to perform creating and handling certificates and related files etc. We can use th OpenSSL tool for many purposes. OpenSSL is dual licensed under an Apache license and a Berkeley Software Distribution license. OpenSSL is written in the C programming language and relies on different ciphers and algorithms to provide encryption. Start the sqlpackage process with the environment variable OPENSSL_CONF set to point to your custom copy of the config file.OpenSSL is a full-featured Open Source toolkit for the SSL/TLS protocol. Instead I would take a copy of the default config file and comment out the problematic sections. For that reason I would not recommend making the change directly to /etc/ssl/openssl.cnf. ![]() It would become problematic later if subsequent updates add real provider config data to that config file. It should have no impact on other packages on your system that use OpenSSL 3.0 and won't impact sqlpackage at all (because it doesn't understand it anyway). So it is safe to comment these lines out. That is because if you have no other providers then the default provider will be loaded and activated by default anyway. But that section has nothing in it (the "activate" line is commented out). It provides the structure so that you can add additional providers if you want and has a section for the "default" provider. The default config file entries for providers (which you seem to have) actually does very little. FIPS validated crypto, or a third party provider such as the "oqs" provider that supplies Quantum safe crypto algorithms). Since you have libssl1.0 (and presumably the matching libcrypto) it doesn't understand these new sections.Ī 3.0 provider contains crypto implementations and enables you to plug in different implementations for different purposes (e.g. All of the provider functionality was added in 3.0 and will not be understood by older versions of OpenSSL. This is an OpenSSL config file that is intended for use with OpenSSL 3.0. I can provide more detailed diagnostics if that would be useful. (provider: TCP Provider, error: 35 - An internal exception was caught) *** A connection was successfully established with the server, but then an error occurred during the pre-login handshake. My question: what is the effect of commenting out the line that I've commented out? Could it lead to security vulnerabilities? Is there a way that I can narrow down my changes to reduce the scope to just what I need?Įrror I see when the openssl_conf. I don't really understand how this config file works. ![]() It seems to be referring to some other sections (which I've left in but are no longer referred to): īased on some other research, I suspect that it's now working because I can make a TLS 1.0 or TLS 1.1 connection (rather than TLS 1.2 only), but I may be way off. I'm running Ubuntu 22.04 and have commented the following line out of /etc/ssl/openssl.cnf: openssl_conf = openssl_init I spent a long time trying to get the connection to work (it was failing with an SSL initialization error) and accidentally stumbled on the following workaround. Background: I'm using a tool (sqlpackage) that relies on libssl1.0 (installed per a StackOverflow answer) to connect to a SQL Server instance running in a Docker container. ![]()
