If it works with VB, and if you have the private key stored in usual Windows
certificate store perhaps your COM has problems to access the private key to
decipher data, because a service has no GUI to access the private key
password.
Also, it could be any other kind of error that happens when your COM has
been called a lot of times, and does not happen when you use it only a few
times. Try to print in the log the parameters you are passing to
RSA_private_decrypt each time.

Subject: A problem using a COM dll built with libeay32.dll
Hi, everyone:
I have a problem. The situation is like this--
I built a project with VC, and the project is a ATL COM project. I
built it with libeay32.lib which I added in the "project
settings->link" , and the "code generation" I chose "Multithreaded
DLL". The COM dll was sucessfully built.
When I use the dll in a VB project or asp, it is normal and have
no problem. Now I put the dll in a directory of a web server using
Windows2000 and added it to the "Component Services". The web server
got the data which was encrypted and posted by other clients , then
web server's asp program created an object of the COM dll and
decrypted the data and returned some messages to clients.
When I check the "Event Viewer's Application Log" of the web
server, I find there are some com error produced by the COM
application.The errors are like this--
The system has called a custom component and that component has failed
and generated an exception. This indicates a problem with the custom
component. Notify the developer of this component that a failure has
occurred and provide them with the information below.
Component Prog ID:
Server Application ID: {4FC68A3D-A240-4133-834A-2CF075B0C543}
Server Application Name: GnetDll
The serious nature of this error has caused the process to terminate.
Exception: C0000005
Address: 0x010A110D
Call Stack:
LIBEAY32!RSA_private_decrypt+0xD
We are sure the error was produced by the COM application because
there are no other program using the libeay32.dll except this.
I put libeay32.dll in the "system32" for that I used static
linking libeay32.lib within my project.
Could anyone know why this happend and how could I solve this
problem? Thanks all.
