The GRIDS Center is pleased to announce the release of PURSe: Portal-based User Registration System, which is now available for download. PURSe is a system for registering users of Web-based applications that use the Grid Security Infrastructure (based on PKI and X.509 certificates). PURSE coordinates the process of establishing Grid security certificates for new users when logging in to an application web site. Users who already have valid certificates can also easily register with the portal applications. By leveraging the MyProxy certificate repository, PURSe shields web application users from the complexities of X.509 certificate management, and enables rapid registration of users.

Installation and downloads:

• Installation instructions
• PURSE's code
• Portal sample code (not required for testing PURSE, but provides an example of how the portal interface code could be written).

To learn more about PURSE, see its entry in the Grid Ecosystem reference guide or download the current user's manual. To see an example of PURSE in use, visit the Earth System Grid Web site and click the Login link. (Note: At the registration web page, please specify in the "Statement of Work" that you are interested in seeing PURSe in action. Access will be granted with limited access to ESG data.)
