Hi,
I am looking to get a reseller account with cpanel/whm and I have questions about ssl.
1. I would like it so that when my clients login that they login through an ssl connection to their hosting accounts
and
2. I would like them to be able to access their email via ssl (e.g. webmail button on cpanel) [e.g to give the option 'Go to Secure Webmail Login')
What type of ssl would I need for this? And is this level of SSL necessary?
Assume for the example that domain is www.mydomain.com.
Thanks.

First of all, I would suggest learning quite a bit more before you resell hosting. Yes, SSL is a bit of it's own area, but it's a very important aspect of this industry. You can do both, and it's not by any means a bad thing, in fact it may be a plus for many.
You can get A rapid SSL for roughly $15/year and see if that fits your needs. They're pretty simple to setup, and most providers have step by step guides.
It's not absolutely necessary but for $15/year mwhy not right? Take a look at: http://www.enom.com/secure/default.asp

Thanks. Let me ask you this then. Where is a good place to start learning?
Also, currently my cpanel hosting account with my shared hosting is ssl enabled. I have the lock in the corner on my control panel, and it says mydomain.com:2083. When I look at the cert itself, the common name is the same as the nameservers of my hosting provider (somewhere.resellerprovide.com). I know this is a self-signed cert from my provider -- but as long as the info is encrypted, I'm not questioning who they are (owning the certificate).
I'd like to recreate this setup on my own reseller account.
To make it clear for me, let's assume that my reseller domain-to-be is myreseller.com How would I setup the same situation for my own hosting clients? -- such that my clients see clientsite.com:2083 and their certificate would have the CN nameserver.myreseller.com? Would I need a wildcard cert for this or would root work?
Thanks for your help.

Well here is one of the best places to learn. More often than not if I google something WH related I end up here anyways, even if it's post years old, it's all good stuff to take in.
Yes you could duplicate what you host has done for you, but better to know exactly what your goal is. Sounds to me like it's a self-branding issues, keeping your host transparent to YOUR customers, right?

Acutally, it really doesn't matter. Transparency isn't the issue. I want the main page where they login to their control panel to be with mydomain.com, but past that, it doesn't matter about the nameservers.
All I care about is that when they login to their control panels that it's through an SSL, and (at mydomain.com), and that when they access email, they can go through webmail in cpanel to a secure webmail connection, or head to webmail.mydomain.com to login.
That's really it.
