Things are at a very early stage and no code is currently publically
available, however...
There are quite a few aims for the ASN1 revision.
One goal is to reduce code bloat. As such I want to avoid any option
that results in lots of code. I'm planning an "intelligent" encoder and
decoder that gets passed a tiny structure describing the ASN1 structure
to encode or decode.
It will be possible to hand code the structures with the aid of various
macros. The result should be much more readible than the current mess
and vastly easier to write.
It should also be possible to post process the output of an SNACC
'template' into these structures too.
Another aim (though not initially) is to support stream based I/O. As a
result it should be possible (for example) to process enormous PKCS#7
structures without ever holding all the content in memory.
Steve.
