Hi Joseph. You can use any simple SSL certificate for this. A plain, standard SSL from GoDaddy would work. My company actually resells very cheap, standard SSLs. If you are interested in a price, let me know and I will give you a quote. Installing it for use with SM is very easy. You would need to export the cert in Base 64 format first. Here are instructions on how to do so...
Once you do that, you would need to specify the ports in SM and link the cert to the ports. Here are instructions on how to do so:
Please let me know if you have any questions. Thanks!
