Others have already provided you with good answers. But since my
favorite approach is missing, I thought I would chime in.
I often use "apt-cache search" for issues like this. For example in this case
% apt-cache search openssl header files
dlang-openssl - D version of the C headers for openssl
lcmaps-openssl-interface - LCMAPS header files for OpenSSL interfaces
libssl-dev - Secure Sockets Layer toolkit - development files
shows that there are three packages that could be interesting.
"apt-cache search" does a full text search on all available package
lists for the given regex pattern. More details in the "man apt-cache"
page.
Now you can read the description of each package ("apa-cache show
<pkgname>") to figure out that libssl-dev is probably what you are
after.
This approach works well if there are only a handful of results. But
if there are too many results, it can be quire tiring to research each
and every one of them. In that case, I pipe the output to
popsort.py[1][2] which sorts the results by popularity. For example
% apt-cache search openssl header files | popsort.py
54043 lcmaps-openssl-interface - LCMAPS header files for OpenSSL interfaces
43941 dlang-openssl - D version of the C headers for openssl
1771 libssl-dev - Secure Sockets Layer toolkit - development files
where the first column shows the rank of the package and the results
are shown in the order of increasing popularity. In this particular
case, libssl-dev is the most popular one. So I would start my research
from there.
[1] - popsort.py is a python program I wrote. It can be downloaded
from https://gitlab.com/d3k2mk7/rutils/blob/master/bin/popsort.py and
requires Python3.
