Thank you. I already knew that one.

The problem is that not the vendors itself add their entries but
normal users enter what they believe is the name and ASN.1 syntax.
Example: Can someone give me the complete ASN.1 syntax of
entrustVersInfo (OID 1.2.840.113533.7.65.0)? E.g. alvestrand.no
says:
entrustVersInfo EXTENSION ::= {
SYNTAX EntrustVersInfoSyntax
IDENTIFIED BY { id-nsn-ext 0}
}
EntrustVersInfoSyntax ::= OCTET STRING
But according to the ASN.1 parser I'm using it seems to be a
SEQUENCE of a string containing the version (e.g. "V4.0") and a BIT
STRING containing some flags.
See output of Peter Gutmann's dumpasn1:
: SEQUENCE {
564 06 9: OBJECT IDENTIFIER
: entrustVersInfo (1 2 840 113533 7 65 0)
575 04 12: OCTET STRING, encapsulates {
577 30 10: SEQUENCE {
579 1B 4: GeneralString 'V4.0'
585 03 2: BIT STRING 4 unused bits
: '1001'B
: }
: }
: }
: }
: }
: }
Ciao, Michael.
