This class acts as a wrapper around the OpenSSL functions provided by the PHP OpenSSL extension, which may be intimidating to those who simply want to use secure encryption, and are unfamiliar with OpenSSL's inner workings.

This class focuses explicitly on data encryption/decryption; other features of OpenSSL such as signing/etc. are not implemented.

This class encapsulates functionality to do the following:

• Generate a private key/certificate pair
• Encrypt data using a public or private key
• Decrypt data using a public or private key
