General

What is JSDSI?

JSDSI is a Java implementation of the SPKI/SDSI standard. It began as Alexander Morcos's Master's thesis at MIT; his code lives on in the "sdsi" Java package. In 2002, Sameer Ajmani reimplemented the Java SDSI API with several improvements and renamed the package "jsdsi." These improvements include full support for SPKI tags, more efficient parsing and marshalling of SPKI/SDSI objects, better testing using JUnit, XML support, and more powerful certificate chain discovery algorithms. JSDSI is now hosted by Sourceforge and has several developers contributing new features like an improved build process and LDAP support.

What is SPKI/SDSI?
