Greetings,

I've been working on a project that requires encrypted communication between two PHP servers. I have recent experience using the mcrypt API, but I'm considering setting up a public key exchange system with the openssl API. I could make either scheme work for me, but my problem is one of popularity.

This would be installed on a wide diversity of PHP servers. Neither mcrypt nor openssl are installed by default, but I was wondering if anyone knew which was more commonly available. Additionally, if you know of a GPL'd native PHP encryption/decryption (2-way) functions or classes, I welcome your input.

Thanks!
