PHP-CA is a simple CA (Certificate Authority) meant to be run by organizations that have a simple need for a CA to issue certificates to employees, without the need for a full scale authority.
Simply put PHP-CA is a basic authority that supports proof of identity by sending an email with a key to a specified email address.
Reciept of this email proves identity and then that person can issue certificates based upon the email address.
The certificates issued can be used as proof of person owning the email address in the signature, and trust of the issuer can be used to allow email address holders to be allowed access to various corporate sites/administration areas.
