* asn1_internal.h
* ---------------
* Library internal header file for ASN.1 routines. These functions
* are not part of the public libhal API.
*
* The only reason for not collapsing this header file into
* hal_internal.h is to maintain some isolation between the few
* modules which use libtfm and the rest of the library.
*
* More than 20 years after it was written, the best simple
* introduction to ASN.1 is still Burt Kalski's "A Layman's Guide to a
* Subset of ASN.1, BER, and DER". Ask your nearest search engine.
