Normally the hash will be something like and md5 of ... time + amount + shared key / password + ID ...
They'll pass a response back to you ... and you'll use your shared key to verify its a real message...
Thats the basics ...
Realex offers a lot ... just drop them a mail asking for details on their APIs available .. or have a look at their site ... (not sure if its publically listed) but they were pretty fast to respond when I was looking before...
SSL certs are normally ... on a domain basis and require a fixed IP address and will only work for that domain .... not a subdomain
www.domain.tld ... would be different to domain.
tld ... and the cert wouldn't work for both.
The level of encryption you opt for is up to you (a lot of the cpanels from irish hosts have a simple process to get these)
