JSDSI / Discussion / Open Discussion: JSDSI .. still active??

Somaya - 2005-10-24

Hi,
I just wonder whether or not this project is still active? I want to use a Java implementation for SPKI certificates so i want to know if there'll be any support if I used JSDSI ?

Thanks,
Somaya

  We're not actively developing JSDSI, but it should still be useful to you, and I at least will still answer questions when I can. But no promises on how queickly or how thoroughly :)

  Okay :)
  Well I want to develop a certificate based trust management system, where entities in the system can issue cerificates, delegate their capabilities, and verify certicertification paths, I found that X.509 certificates won't be appropriate as it doesn't support delegation, moreover it just supports identity certificates, So would a SPKI implementation like JSDSI be useful for me?
  
  One more question, Does JSDSI implementation replys on Java security APIs architechture, more spceifically the Java Certification Path API, or it is totally independent?
  
  Thanks in advance,
  Somaya

  I developed the cetr path discovery algos for JSDSI, and I've done my best to make it implement Java's security APIs, including the Certification Path API. So the short answer to your question is "yes, I think so".
