Signing Process
Signed Certificate Project
Uniform Server 3.5-Apollo

With our domain verified and CSR (certificate signing request) created its time to look at CAcert's signing process. In reality its just a two-way copy and paste exersise. The following is a continuation from the previous page hence the section numbering

Step 3) Signing Process

The file server.csr is referred to as a CSR (certificate signing request) it contains our unsigned server certificate. The following provides detailed steps required to get it signed at CAcert:

1) Login

Go to CAcert's home page, to the right under under My Account click Password Login

At the login page enter your Email Address and Pass Phrase click Login.

Using a text editor open the file server.csr located in folder:

*\Uniform Server\udrive\home\admin\www\plugins\uc_mod_ssl\key_cert_gen

and copy the contents to form shown on the right.

Click Submit this starts the signing process.

Confirm this is correct by clicking Submit.

5) Certificate generation

After a short time your signed certificate is displayed and a conformation email sent to your registration email address.

Using a text editor open the file server.crt (Location: *\Uniform Server\udrive\usr\local\apache2\conf\ssl.crt ), delecte it's content.

Copy your signed server certificate (see right) into it and save.

For the certificate to take effect re-start your server.

Obtaining a signed certificate really is that easy copy and paste twice.

Real world experience

I have included this section because things do not always run smoothly when this happens you need support. I was extremely impressed with CAcert’s support team and would like to express my thanks to Teus and Philipp.

The registration process was relatively easy I confess to having several attempts at a valid pass phrase.

First experience obtaining a signed server certificate, I originally used my registered domain name and pointed the MX records to my ISP’s mail sever the whole process ran flawlessly.

My real goal was to use a free dynamic IP service such as DynDNS and No-IP. This requires running a local mail server and that’s where I had some problems. Verification failed using OM3, thinking CAcert blocked the above services I put in a support request and found they don’t. OM3 is still in beta; hence I tried Mercury mail transport as an alternative. This passed the mail probe test however I noticed a few strange characters in the conformation link. I removed these and obatained validation.

Thinking there was a problem sent in another support request, the reply and solution was fast and spot on. This is where I become a little red faced; I was not using a mail client for reading the email. Being lazy I used a text editor to directly pickup the information from the account file, whoops including those strange (MIME) characters. From the sparse inform I sent CAcert support they suggested I use a mail client; spot on they probably realised what I had done. I checked using a mail client confirming my problems were self-inflicted. Note for Xamp users you will have no problems using Mercury mail transport.

Wanting the whole process sequence to be a smooth and uneventful experience when using Uniform Server I decided to include hMailServer. That decision was correct, installed with no problems, easy to set-up and it sits there working. One side effect! I could not resist the temptation to play with a new bit of kit hence the PHP mail function page.


I had several objectives for this project. Primary objective run a secure server with a genuinely free-signed server certificate amply met by CAcert. Secondary objective introduce new material providing real alternatives in particular mail server and a solution to having a dynamic IP address. I met this target using hMailServer this certainly will remain on my PC as for No_IP it does what it is intended to do however because they charge for a wildcard domain its back to DynDNS for me.

I am personally unhappy with the lockdown section, security is of prime importance and I feel this section is to open and general. Would liked to have been specific and state your PC is now secure however for the reasons I provided in the section not a chance.
