<p class="MsoNormal">Hi Team,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our team has started migrating from OpenSSL 1.0.2 to OpenSSL 3.0.x version.<o:p></o:p></p>
<p class="MsoNormal">We are doing POC for the same on windows and Linux.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a tight schedule to finish the migration by April 1<sup>st</sup> week as we need to fix one critical BD issue and support TLS 1.3 feature as well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The team and I are going through multiple docs of OpenSSL 3.x and trying to figure out how to configure fips once we build the OpenSSL.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Few things:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">In openssl 3.0.x Fips module is installed/integrated by default (enable-fips) during the build step<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Fipsmodule.cnf is present in the default location (c:\usr\local\ssl\)<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">After reading multiple ways on how to enable fips, one way is the config way where we need to change few params in openssl.cnf<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">By changing that and we did the test using openssl.exe ( sha1 passed and md5 failed) all good<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Now the challenge is we need to set the fips enablement programmatically which we were going through multiple docs (openssl and some forums)<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Till now we used OpenSSL 1.0.2 where the fipsmodule is embedded in libcrypto and we need to set it at the beginning of the application (fips_mode_set()) and everything else is taken
care by default.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Now with OpenSSL 3.0.x how to set that fips mode for the entire application is not very clear<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Very where they are talking about the config files, our application is a standalone application that bundles all the required libs(crypto/SSL) and runs on its own, it will not refer
to any system config/lib files<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">So our doubt is if we build on the application on build machine containing OpenSSL 3.0.x and create an artifact. We need to run on different machines.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">In OpenSSL 3.0.x is there any hard dependency on the .cnf files should we carry them in our artifact and if so should we install them in the default path like ( C:\usr or /us/local)
which we were not doing till now?<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any input on this will be really helpful<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
