Hi,
I need to make sure that only a certain assembly has access to a specific certificate.
Is CAS the way to go or there is a simpler option?
In case it is CAS how do I do to deny access to this certificate to any other assembly?
Also I didnt find the granularity of a certificate, the most granular is X509 Store and it doesnt refer to one specific store it refers to all the stores.
Any help with this is more than welcomed.

Regards,

Hi,
I just mean that there is no 100% safe encryption methods, so, contrasting with the best encrytion algorithm, we'd betterchoose the one that enough for us.
By set up NTFS security, you may set access permissions of a file to limit who can read/write it.

Thanks,
Eric

Hi,
CAS cannot help for your case, you may want to embed the file into your assembly, or decrypt before read and encrypt after save, re-read the business goal may help you to find better way.
However, we cannot 100% prevent other from accessing physical files, the file can be read or modified by other hack tools.

Hi eryang,
Thanks for your response.

So you are saying that basically there is no secure way of protecting a Private key in the file system?

Thanks,
