*To*: SPKI List <spki@c2.net>*Subject*: Question*From*: JoanMa Mas Ribés <mas@tele.ucl.ac.be>*Date*: Thu, 29 Apr 1999 19:54:01 +0200*Organization*: UCL - TELE http://www.tele.ucl.ac.be*Sender*: owner-spki@c2.net

List, I've started implementing a SPKI toolbox in Java, and right now I've a question (which won't be the last) about comparing principals. If I've understood it correctly, the field <uris> in a public key is used to point where you can get certificates on that key, right? I guess that the <uris> field in the hash has the same purpose, when this hash is of a public key. The question is, how do I compute the hash of a public key? I mean, should one take the s-expression representing the whole key (uris included)? If so, should I copy the <uris> field from the key into the hash? And when comparing principals for "samePrincipalAs", do I take into account also the <uris> field? If the answer is yes, then a principal is not only a public key or hash, but also the <uris>, which has the problem that we'd have 2 different principals represented by the same key but with different <uris> field. And if not, then computing the hashing of a public key is a special case in SPKI (it'd only be some more lines of code), which would first remove the <uris> field in the public key, compute the hash and add <uris> in the hash. I hope I made myself clear. Thanks a lot in advance.
