How would I go about making and implementing self-signed SSL certificates for a server? I am running RedHat Linux 6.2 with Apache and CPANEL. If someone could point me to a resource of how this is done, or help me with some step by step command lines, I'd really appreciate it. Thanks for the help.

First you need to generate a key:

openssl genrsa -rand randfile -out key.pem 1024


And to generate a untrusted certificate:

openssl req -new -key key.pem -out cert.pem -x509


cert.pem is the certificate you would install...

Thanks! Now how do I correctly install it? I have WHM..
This is the output after I did what you said
---------------------
root@univex [/]# openssl genrsa -rand randfile -out key.pem 1024
0 semi-random bytes loaded
Generating RSA private key, 1024 bit long modulus

e is 65537 (0x10001)
root@univex [/]# openssl req -new -key key.pem -out cert.pem -x509
Using configuration from /usr/share/ssl/openssl.cnf
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:UTAH
Locality Name (eg, city) []:SALT LAKE CITY
Organization Name (eg, company) [Internet Widgits Pty Ltd]:DIATONE.NET Inc.
Organizational Unit Name (eg, section) []:Web Hosting
Common Name (eg, your name or your server's hostname) []:UNIVEX
Email Address []:brad@diatone.net
root@univex [/]# locate cert.pem

In WHM it says I need to paste the .key file and the .crt file.. Just a little bit more help.. Thanks alot.

You now just pico/vi the key.pem, and paste the contents into the WHM .key section, then pico/vi the crt.pem and paste it into the .crt second in WHM, enter the IP, domain, and user of the site, and hit install....

Duh, ok. Thanks :D
One more thing, do you know if it is possible to make it not display the warnings? Like the security certificate was chosen by a company you do not wish to trust, blah blah. I think it would be possible, because I think I've seen it done before.

Also, when I go to https://www.diatone.net now, it displays the warnings and all, but it won't display the page.. know why?

Most probably you are using IE, and the domain on your certificate is not resolvable by DNS.

it is a self signed certificate, it will display warning on all browser. to remove to warning you will have to purchase the certificate instead of self signing one

You have to have it signed by thawte, verisign or a company that IE is pre-configured to trust.

The error is a 404, are you sure the site is pointing to the right directory (talking from an IIS point of view here) ?

Well, the regular http://www.diatone.net works.. so.. yea, it is pointing to the right directory.
