VS: [Mono-list] Problems with CRLDistributionPointsExtension

[Hellan.Kim KHE]

Hi Sebastian

Thank you (again)!
Do you have any example code about how I can parse the ASN.1 myself?
All I need is the Directory Access value in plain text, but
unfortunately I don't know anything about ASN.1.

I have now moved almost all my code from using OpenSSL to Mono regarding
the certificate handling, and this Directory Access value is the very
last thing I need to implement before I can dump OpenSSL.

ANY help appreciated :-)

/Kim

PS!
X509Extension ex =3D x509.Extensions ["2.5.29.31"];
...works just fine.

Hello again Kim,

IIRC you can do

X509Extension ex =3D x509.Extensions ["2.5.29.31"];
if (ex !=3D null)
	cdpExt =3D new CRLDistributionPointsExtension (xe);
...

The DistributionPoint SEQUENCE (inside the CRLDistributionPoint) isn't
decoded.

Sadly it's been a while since I've worked on this code. I will
eventually
resume this to support CRL and other Fx 2.0 features but until then only
the
features that Mono required elsewhere are implemented.

a.	Contribute the code :-) or
b.	Fill a bug in bugzilla.ximian.com, attach sample code and a
sample
