1.0 What is x509viewer?
-----------------------

x509viewer is a simple command line application, written in Perl, that can be
used to decode one or multiple X.509 certificates per given file, such as e.g.
SSL certificates, CSRs (certificate signing requests), but also private keys.


2.0 Requirements
----------------

- perl >= 5.6.0
  - perl >= 5.8.0 is recommented to avoid possible problems
  - perl modules Fcntl, Getopt::Long and IPC::Open3
- openssl >= 0.9.5
  - openssl >= 1.0.1e (current latest stable release) is recommented


3.0 Installation and configuration
----------------------------------

Extract the x509viewer-X.Y.Z.tar.gz using "tar xvfz <file>" or "gzip -d <file>
&& tar xvf <file>" for example. "X.Y.Z" simply stands for the current version
number of x509viewer.

After that, change into the directory and type "make install" for installing.
