SCEP client implementation .net 2008 c# - Help

[Guest Kinslayeruy]

hello,

i'm trying to implement a SCEP client library for the use of my

company.

I've read the scep draft and the rfc's related to the topic, then

tried to use xenroll.dll (i'm using windows xp) to create a pkcs#10

message, but the CA's don't seem to recognize it (testing against a

Cisco IOS CA and a Windows Server 2003 Standard CA with the MSCEP

addon).

Then i tried to envelope this message with the EnvelopedCms

(System.Security.Cryptography.Pkcs.EnvelopedCMS) to make a pcks#7

envelope around it, but i couldn't found how to add the necesary

authenticated attributes.

I then tried many other thins (even a openSSL wrapper) but can't find

the way to make this work.

 

If you know of a working implementation of a scep client (in dll or

command line format) that works in both winXP and vista, against a

cisco router, please let me know (both opensource or paid

implementations are welcome)

 

thank you for reading, hope you can help,
