Compile OpenSSL

Written by  on Dezember 20, 2015 

Most distributions contain only an old version of openssl. If you need a newer version for your scripts, ther often is no other way than compiling it from source. Here I’ll show you, how to do it. And don’t be afraid, it’s super easy! The latest version is a 1.1 development version.
There are only a few prerequisits: You need the packets make and gcc. First you download the source from github and unpack it:

wget https://github.com/openssl/openssl/archive/master.zip
unzip master.zip
cd openssl-master

You simply do the steps for compiling software on unix/linux:

./config
make
make install

You need to do at least the 3rd step as root, so it can install the files for you. By default, everything gets installed into /usr/local/ssl – so it won’t destroy your system OpenSSL.

# /usr/local/ssl/bin/openssl version
OpenSSL 1.1.0-pre2-dev  xx XXX xxxx

Have a lot of fun!
