Unable to read the X509Certificate2 private key

    Question

  • Hi,

    I am using an X509Certificate2 [PFX] and I am getting this certificate read from the My / CurrentUser Store in Microsoft Azure AppService [Not Web Role]. In case of the application trying to restart after a idle timeout, it seems that the certificate looses its private key and I am not able to decrypt the messages.

    Is there any specific change to be done in the Azure AppService other than uploading the certificate to make sure that the certificate's Private key is readable internally.

    Even tried to use a private blob for this and got the "Key Set Not Found" exception in both the Certificate Store & the BLOB Storage. 

    I am not sure why the private key is lost all of a sudden and why would the exception be thrown. Kindly suggest a fail-safe method. I assume that even with this case, opting for use of a Azure Key Vault would not stop the errors from coming up.

  • Oopsie,

    My Microsoft Authentication failed in that site, guess that's a completely different model. Finally got it working with Google Auth. 

    I am reposting this question there. Thanks @Wendy
