Can anyone please tell me what is OID 1.3.6.1.4.1.311.21.10?
This appears to be Microsoft specific - 1.3.6.1.4.1.311.21 is assigned to
Microsoft CertServ Infrastructure.
I want to know how do I handle this OID in my parser. I converted .PFX to
PEM and I am parsing the PEM file. The PEM file has this OID. My parser is
running on a non-windows client. This parser is neither OpenSSL nor derived
from it. I want to know how do I handle this OID - what is this extension?
OpenSSL was not able to put a name to this OID.
Searching the web I found some limited information - it has 2 Elements -
Flags and Length. Some kind of store for Application Policies? PFX->PEM was
for a EAP-TLS - here are some of the x509v3 Extensions from that
certificate.
X509v3 Key Usage:
Digital Signature, Key Encipherment
X509v3 Extended Key Usage:
TLS Web Client Authentication
1.3.6.1.4.1.311.21.10: critical
0.0
Thanks

From wincrypt.h (from platform SDK):
// Application Policies extension -- same encoding as szOID_CERT_POLICIES
#define szOID_APPLICATION_CERT_POLICIES "1.3.6.1.4.1.311.21.10"
As far as I understand it - this is Microsoft extension that allows or
disallows aplying application defined policies to certificate templates. You
surely can ignore it.
