Dear reader, like myself, you have intensively read the man pages of the applications of the OpenSSL project, and like myself, you couldn't figure out where to start, and how to work securely with certificates. Here is the answer to most of your questions.
This HOWTO will also deal with non-linux applications: there is no use to issue certificates if you can't use them... All applications won't be listed here, but please, send me additional paragraphs and corrections. I can be reached at the following address:firstname.lastname@example.org.
This HOWTO is published on The Linux Documentation Project this is where you will find the lastest version of this document.

As indicated in the introduction, this documents is an hand-on HOWTO, and it is therefore required that you consult the man pages of the OpenSSL software. You should as well read security books to learn how your security could be compromised. Certificates are meant to increase the security of your transactions, it is VERY important that you understand all the security implications of your actions and what security OpenSSL does not provide.
