oh. did i meet you there? i was contracting at RSADSI at the time and argued w/ Burt K. about how easy it was to mess up a general DER parser, much less an ASN.1 compiler. I remember we found about two bugs per week in ICL's compiler. Burt and Ron were BIG ASN.1 fans at the time and I could never figure out why. Ron kept pushing Burt and Bob Baldwin to include more generic ASN.1 features in BSAFE. Part of my misery during SET development can be directly traced to ICL's crappy ASN.1 compiler, yet it was probably the best one on the market at the time. Anywho... XDR isn't my favourite, but I would have definitely preferred it to DER/BER/ASN.1. Stop me before I make a CORBA reference. | ||||||||||||||||||||||||||

> oh. did i meet you there? Probably :-). Ron was a huge fan of Roger Needham's (and, ngl, I was too) and Roger along with Andy Birrell and others were on a kick to make RPCs "seamless" so that you could reason about them like you did computer programs that were all local. Roger and I debated whether or not it was achievable (vs. desirable) at Cambridge when we had the PKI meeting there. We both agreed that computers would get fast and cheap enough that the value of having a canonical form on the wire vastly outweighed any disadvantage that "some" clients would have to conversion to put things in a native format they understood. (Andy wasn't convinced of that, at least at that time). But I believe that was the principle behind the insistence on ASN.1, determinism and canonical formats. Once you built the marshalling/unmarshalling libraries you could treat them as a constant tax on latency. That made analyzing state machines easier and debugging race conditions. Plus when they improved you could just replace the constants you used for the time it would take. | ||||||||||||||||||||||||||
