<title>Introduction to <application>Open<acronym>SSL</acronym></application>
</title>

<para>The <application>Open<acronym>SSL</acronym></application> package 
contains management tools and libraries relating to cryptography.  These are 
useful for providing cryptography functions to other packages, notably 
<application>OpenSSH</application>, email applications and web browsers (for 
accessing <acronym>HTTPS</acronym> sites).</para>

<title>Installation of <application>Open<acronym>SSL</acronym></application>
</title>

<para>Install <application>Open<acronym>SSL</acronym></application> by running 
the following commands:</para>

<screen><userinput><command>patch -Np1 -i ../openssl-&openssl-version;-fix_manpages-1.patch &amp;&amp;
./config --openssldir=/etc/ssl --prefix=/usr shared &amp;&amp;
make MANDIR=/usr/share/man</command></userinput></screen>

<para>To test the results, issue: <command>make test</command>.</para>

<para>Now, as the root user:</para>

<screen><userinput role='root'><command>make MANDIR=/usr/share/man install &amp;&amp;
cp -r certs /etc/ssl</command></userinput></screen>

</sect2>

<sect2>
<title>Command explanations</title>

<para><option>no-rc5 no-idea</option>: When added to the
<command>./config</command> command, this will eliminate the building of those
encryption methods. Patent licenses may be needed for you to utilize either of
those methods in your projects.</para>

<para><command>make MANDIR=/usr/share/man; make MANDIR=/usr/share/man 
install</command>: These commands install 
<application>Open<acronym>SSL</acronym></application> with the man pages in 
<filename class='directory'>/usr/share/man</filename> instead of 
<filename class='directory'>/etc/ssl/man</filename>.</para>

<para><command>cp -r certs /etc/ssl</command>: The certificates must be copied 
manually since the install script skips this step.</para>

<sect3><title>Configuration Information</title>

<para>Most people who just want to use 
<application>Open<acronym>SSL</acronym></application> for providing functions
to other programs such as <application>Open<acronym>SSH</acronym></application> 
and web browsers won't need to worry about configuring 
<application>Open<acronym>SSL</acronym></application>. Configuring
<application>Open<acronym>SSL</acronym></application> is an advanced topic and 
so those who do would normally be expected to either know how to do it
or to be able to find out how to do it.</para>
