It is never recommended to upgrade you distribution's version of OpenSSL with one you compile yourself. Doing so will often break all software installed by the distribution that uses it.
If you need functionality from newer versions of OpenSSL, your options are to upgrade your OS version, or to install a local copy of OpenSSL and manually compile and link local copies of the applications that need the newer functionality. (Newer versions of OpenSSL do not maintain the same Application Binary Interface (ABI), which means that binaries compiled against older versions will not correctly operate or dynamically link against newer libraries. Also, distributions such as Debian can modify the ABI in such a way that nothing distributed directly by openssl.org can be compiled to meet it without source code modification.) -Kyle H On Wed, Aug 5, 2020, 14:49 Patrick Mooc <patrick.m...@gmail.com> wrote: > Hello, > > I'm using an old version of OpenSSL (0.9.8g) on an old Linux Debian > distribution (Lenny). > > Is it possible to upgrade OpenSSL version without upgrading Linux Debian > distribution ? > If yes, up to which version of OpenSSL ? > > Are all versions of OpenSSL compliant with all Linux Debian distribution ? > > > Thank you in advance for your answer. > > Best Regards, > >
