BBN has created three ASN.1 code generators over time and even released a co=
uple. (ASN.1 to C, C++, and Java). I believe that DER to support typical X.5=
09 management is the easiest subset. I can check on status for release to o=
pen source if there is interest. It has been available as part of Certificat=
e Management systems we've released to open source but obviously this is a v=
ery small COI indeed.
I can read hex dumps of ASN.1 and choose not to develop similar skills for X=
ML and other types. I'm getting too old for that kind of skill acquisition=
to be fun. But to forward reference in this chain (with apologies), I too w=
ould prefer a standard that that has Postel's principles as a touchstone.=20=
