Securing a X509Certificate RRS feed

  • Question

  • 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 better choose 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.

    Thanks,

  • 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,
