Hi Robert, If your only reason to migrate is to mitigate an OpenSSL vuln, you can try to replace the openssl.exe binary and the DLLs used in your currently working Stunnel version. Since there is no compatibility breaking changes in latest OpenSSL releases, Stunnel should be able to load it without complaining. I currently do this with the 1.1.1 branch, and it is working flawlessly so far :) Can't say for sure for the 3.0.0 branch, but it's worth a try.
You can find up-to-date pre-built binaries here: http://wiki.overbyte.eu/wiki/index.php/ICS_Download#Download_OpenSSL_Binaries_.2 8required_for_SSL-enabled_components.29 Other options are also listed on the official OpenSSL wiki: https://wiki.openssl.org/index.php/Binaries Best regards, Florian Stosse Information security engineer Safran Electronics & Defense | Safran Data Systems | Space & Communication > -----Message d'origine----- > De : robert.croteau--- via stunnel-users <[email protected]> > Envoyé : vendredi 15 avril 2022 09:21 > À : [email protected] > Objet : [stunnel-users] Windows service won't start.
