Our asn1_print, like OpenSSL's, just knows how to parse and dump DER.
Ours can attempt to decode OCTET STRING and IMPLICIT-tagged constructed
values as DER, which is very useful.
But _now_ it's even better. Now it knows about all types exported from
all ASN.1 modules in `lib/asn1/` in Heimdal, and if told to print as
some type, it will use the new printing interface to print JSON-like
representations of values:
```
$ ./asn1_print /tmp/t490/ek2.crt Certificate |
jq '.tbsCertificate.extensions[3]._extnValue[]._values'
[
{
"_type": "TPMSpecification",

.Sh DESCRIPTION
|
|
.Nm
|
|
Dumps ASN.1 DER-encoded values.
|
|
If a
|
|
.Ar TypeName
|
|
is given, then
|
|
.Nm
|
|
will print the value in a JSON-like format using its knowledge of
|
|
the ASN.1 module defining that type.
|
|
If a
|
|
.Ar TypeName
|
|
is given, it must be the name of an ASN.1 type exported by an
|
|
ASN.1 module that is compiled into
|
|
.Nm .
|
|
Use the
|
|
.Fl Fl list-types
|
|
option to list ASN.1 types known to
|
|
.Nm .
|
|
.Pp
|
|
Options supported:
|
|
.Bl -tag -width Ds
|
|
.It Fl i, Fl Fl no-indent
|
|
Do not indent dump.
|
|
.It Fl I, Fl Fl inner
|
|
Try to parse inner structures of OCTET STRING and constructed values.
|
|
.It Fl l, Fl Fl list-types
|
|
Try to parse inner structures of OCTET STRING and constructed values.
