 Problem Description:

 SCEP error during cert enrollment

Hi I´ll try to get SCEP interface on my OpenCA installation to work.
I created a cert for the SCEP RA as role Webserver.

I tried to get it with following devices

Linux with SSCEP ,
Cisco VPN3000 with OS 4.7
Cisco Router IOS 12.3.10a
VPNClient on WinXP 4.6.0.3

I can retrieve the CA cert with all devices, but when I try 
to enroll a cert I fail with all different devices.

It seems that the upload of the CSR just went fine, cause I see
the Certs in the RA interface and I can approve them and sign them in the
CA.

But the client are never able to retrieve the issued cert afterwards.

I can`t see any useful in the OpenCA logs.

The only useful debug I got from sscep client (see below) but a google
search for the error
only revealed problems with false openssl versions.
But as you can see I use openssl 0.9.7e which should be fine

ssep debugging :
./sscep: PKCS#7 contains 0 bytes of enveloped data
./sscep: verifying signature
./sscep: error verifying signature
18051:error:0407006A:rsa routines:RSA_padding_check_PKCS1_type_1:block type
is not 01:rsa_pk1.c:100:
18051:error:04067072:rsa routines:RSA_EAY_PUBLIC_DECRYPT:padding check
failed:rsa_eay.c:580:
18051:error:21071069:PKCS7 routines:PKCS7_signatureVerify:signature
failure:pk7_doit.c:838:

On the cisco devices, I can´t see any useful output in the debugs, only that
there was an error  :-)

Maybe somebody has a hint for me, or can tell me how I can debug this issue
further 

Kind regards
Michael
