Hello,

I installed OpenSSL in which it corrected the errors below with "make testlong"

sage -t --long src/sage/repl/notebook_ipython.py # 9 doctests failed

./sage -i openssl

./sage -f python

make ssl

Anyways, my question is with OpenSSL installed even without the intention to use it, is the machine vulnerable to any future issues or do I have to actually configure and enable it?

Thanks, TT

OpenSSL is currently in a pretty bad state, it is quite frequently updated, and as with any other software, it is much likely that some bugs will appear "in the future". OpenSSL is sometimes used by Sage, for example when you use the sage -pip command, so you can not completely avoid its use. Of course, you can build Sage without SSL and those features will not be available.

Also, the Sage openssl package is here in case your distro does not provide it (or if you are not root to install it). We try to keep it up-to-date. If you don't want do be worried about updates and are using a mainstream distro and have enough administration rights on the machine, you should better install the libssl libssl-dev packages that will automatically benefit from the upgrades provided by your distro.

I installed with the command ./sage -i openssl (so I assumed I used the sage one). So in the future, how would I upgrade it? Same with ./sage -i openssl?

Second questions is if I install libssl libssl-dev now, will it break sage?

Thanks, TT

If you want to upgrade openssl after upgrading Sage (for a given version of Sage there is only a single version of OpenSSL), you can just do sage -f openssl to force reinstallation. For the second question, i am pretty sure the answer is "no", installing those packages should not break you current Sage installation.
