New from the PHP Web Services blog today there's a post showing you how to set up Apache 2.2 for HTTPS connections to consume other web services.
The tutorial gives you a step-by-step process to follow with commands and configuration changes every step of the way:
- Create a certificate
- Generate a key
- Sign the key with the certificate
- Copy the keys to the right directory
- Make configuration changes for the SSL connections
- Connect to the remote HTTPS web service
If you're using PHP, you can also use the OpenSSL and SOAP clients with the SSL libraries to make requests to secure remote resources.
