COMU Privacy Guard

CPG stands for COMU Privacy Guard. It is a security tool. In essence it is a web based shell of Gnu Privacy Guard. It enables users to perform main functions of GnuPG on the web.

CPG has two branchs:
  • The first one must be installed on an email server. Log-in process of this branch uses /etc/passwd. Hence, just real users of the email server can use CPG.
  • The second branch can be installed on any web server that does not need to be an email server. Log-in process of this branch uses MySQL database. Hence anyone can be a user of CPG with any name or any email address.

    It is currently for Linux, Apache webserver and gnupg-1.0.6-5 only.
